What to learn first when you learn chemistry, and how to learn chemistry at the beginning

First of all, you have to cultivate an interest in chemistry, and if you have interest, you will naturally be motivated.

Secondly, it is necessary to pay attention to the study of textbooks, and the teacher must remember what you remember, rest assured, the things in chemistry are easy to remember.

Then, it is necessary to organize the knowledge by yourself, which is very important, not necessarily to write it out, but to think about it often in your head, so that it can be connected before and after; Finally, it is a very important review, which must be in place. You don't need to learn anything first, as long as you are interested, you can definitely learn it well.

It's about interest. If you don't understand, ask questions, don't ask questions, ask questions, ask questions, ask methods. If you do this, your chemistry grades will soon be up.

You should be a high school student.

1.I remember that the definition of chemistry in junior high school was that chemistry is a basic science that studies the composition, structure, properties and changes of matter, so you grasp these in the overall idea.

2.There is still a lot of content to memorize in high school chemistry, so it is recommended that you memorize some of the most basic things first. For example, the properties of matter, reactions, etc. (you want to ask where to start first, but the topics of chemistry are basically comprehensive, including the knowledge of each chapter and section, so you have to keep your feet on the ground.)

However, it is recommended that you first look at some theoretical things, such as the periodic law of elements, and then combine them with the study of each main group element).

3.Do more questions and learn to understand them.

I think it is important to understand what chemical reactions and physical reactions are first, and then to learn elements, chemical programs, and calculations. It shouldn't be a problem to learn these basics well! That's how I learned, and that's how my teachers taught.

Directly from the phenotyping of chemical elements, each group of elements has relevant properties, which is easy to grasp.

From elementology, the properties of elements and elementals.

Remember elements 1-18 first! The basic properties of common elements!

Properties of elements and elements.

1. Clarify the purpose of learning chemistry. Chemistry is a natural science, a compulsory subject in middle school, and it is the achievement of chemical science research and practice of countless Chinese and foreign chemists throughout the ages.

2. Preview before class. The day before class, be sure to take time to consciously preview what the teacher will talk about the next day. Learn to study first and then listen to the lectures.

3. Listen to every class. Listening to lectures is the core part of the learning process, and it is the main way to learn and master knowledge. Whether you can master the knowledge learned well in the classroom is the key to determining the learning effect.

4. Take good notes. To learn chemistry well, note-taking is also an important part. In addition to focusing one's attention and improving the efficiency of listening to lectures, note-taking is also a great help for post-class review.

6. Review in time after class. The content of a class can be reviewed in more than ten minutes, and sometimes it can be repeated like a "movie". Review deepens understanding and reinforces knowledge.

7. Complete the homework conscientiously. Doing homework is an excellent opportunity to practice and one of the important means of consolidating knowledge. Be sure to do it yourself, and never copy other people's homework.

To learn chemistry well, rote memorization is not advisable, the key is to master the method!

There is a lot to remember and a lot to calculate in chemistry. Junior high school chemistry is mainly qualitative, and there are many things that need to be memorized; In high school, chemistry is mainly quantitative, and there are many topics that need to be calculated. Therefore, in order to learn chemistry well, you must not only memorize a lot of content, but also master the method of calculation.

There's a good way to do it with chemistry rote. For example, use homophonic memory, mantra memory, etc. The teacher will also summarize a lot of mantras for the students, which is easy to remember.

For example, the elemental valency formula: "Monovalent potassium, sodium, hydrochloride, silver, divalent oxygen, calcium, barium, magnesium, zinc, aluminum, trisilicon, tetrasulfur, 246, 35 valence, nitrogen and phosphorus, iron, 23, carbon, 24, copper, mercury, 1, 22 valence." ”

High school chemistry has a lot of content and a lot of knowledge points. It is necessary to process and refine knowledge from time to time, and construct it according to its internal laws, so that knowledge that seems to be chaotic can be structured, organized, and systematized. In this way, the textbook can be changed from thick to thin, and the knowledge can be easily grasped and applied.

For example, compare similar knowledge and distinguish their similarities and differences; Summarize regular knowledge; Summarize the common knowledge and make it a knowledge block; Connect connected knowledge to make it a knowledge network.

In the study of chemistry, the purpose of digesting knowledge and improving ability should be achieved through regular practice. Exercises should be timely and appropriate, and fully use various forms such as written answers, oral answers, and experimental operations. It is necessary to repeatedly contact a variety of question types such as choice, fill in the blanks, inference, proof, identification, and calculation, so as to consolidate knowledge, train thinking, and cultivate ability.

It is necessary to give full play to the effectiveness of each question, touch on the analogy, and draw inferences from one example. Some problems can be solved more than one problem, which can open up the idea of solving the problem and improve flexibility; Some problems can be solved in one problem, highlighting the essence of the solution and deriving the law of the solution.

As for the experiment, first of all, the class should carefully observe the operation and experimental phenomena of each demonstration experiment made by the teacher. Secondly, we should pay attention to life and link theory with practice. The material world we live in is closely related to chemistry everywhere and at all times.

We need to learn to think analytically. It is necessary to be good at thinking from the individual to the general, from the phenomenon to the essence, from the special to the law, to grasp the essence behind each experimental phenomenon, and to understand the principle of each key step, so that we can draw inferences from one case and not be afraid of difficulties.

Don't memorize the new knowledge in isolation, but organically connect the old and new knowledge to remember. For example, when learning redox reactions, it is necessary to memorize them in connection with the knowledge of valency learned earlier, which not only consolidates the old knowledge, but also deepens the understanding of the new knowledge. The knowledge that must be memorized is very easy to remember if it can be condensed into a song recipe and catchy.

For example, the valency of the elements can be compiled: "monovalent potassium, sodium, hydrochloride, silver, divalent oxygen, calcium, barium, magnesium, zinc, aluminum, trisilicon, tetrasulfur, 246, 35 valence, nitrogen and phosphorus, iron, 23, carbon, 24, copper, mercury, 12 and 2 valent up. Another example is the key points of the experiment on the reduction of copper oxide by hydrogen can be compiled into:

Hydrogen is turned on first, then the lights are lit, and the heating is stopped and then the hydrogen is stopped.

Answer: 1. Understand the various reaction chemical reactions, including reduction reactions, oxidation reactions, chemical synthesis reactions, decomposition reactions, acid-base neutralization reactions, etc. In chemical reactions, we must firmly grasp the change of valency, and knowing this, I believe that it is not difficult to react. 2. Doing as much experimental practice as possible is the only criterion for testing the truth, so experiments also account for a considerable proportion.

You need to understand the use of some experimental equipment, such as: condenser tubes, test tubes, iron frames, alcohol, etc. In addition, when doing experiments, you must pay attention to your own safety.

3. Before class, the teacher will often talk about the difficult and easy to mix points, and before the teacher speaks, you must prepare for the preview. 4. Connect the knowledge points of life and learning, and connect them with actual life. For example, iron rusts because iron undergoes a slow oxidation reaction in the air.

Dear, the most important thing is to be interested in chemistry, the chemical reaction itself is a strange question What should I do if my child is in his first year of high school this year and is not solid in chemistry in junior high school?

Chemistry is a science subject, and if you want to learn chemistry well, you must first lay a good foundation. Chemistry is not a purely back-to-back subject, but there are some chemical equations that must be mastered. There are also some technical things, such as cross-trimming in redox.

There are also the three major conservation in salt hydrolysis and the various reactions of functional groups in organic chemistry, which need to be practiced continuously.

If you find it difficult to study chemistry, you can find a chemistry teacher and find some ways to do the problems. You must know how to ask for help and find a suitable method in doing the questions in order to effectively improve your chemistry scores.

There are many knowledge points in chemistry, so first of all, we must be familiar with the knowledge points, and secondly, we must conduct more hands-on experiments, observe more and think more to understand.

To learn chemistry, you must first develop an interest, which is very important!

Second, follow in the footsteps of the teacher. You can't think about doing your own thing.

Of course, you also need to do more exercises, which can consolidate your memory and improve your ability.

Pay attention to junior high school: the trim of the equation, the name of the instrument, the acid-base salt, these are the most important.

Chemistry this thing, the knowledge is particularly trivial, but there are strong laws, if you master the law is very easy, in other words, we must remember the theory of things, in order to change everything, everything to remember is impossible, master the theory, many things can be deduced by themselves, for example, redox reaction, the change of valence is clear, many chemical reactions can be introduced formulas, no need to memorize, no need to remember, just master the method, live and learn. For example, the reaction of hydrogen sulfide and sulfur dioxide, according to the theory of redox, obviously produces sulfur. There is also chemical equilibrium, it is very important to grasp the theory, of course, the basic properties of some substances still have to be memorized, but there are also laws to follow, the chemical properties of the same group of elements must be similar, the reason why they are different is mainly because of the number of electrons outside the nucleus, because, the more electrons outside the nucleus, the larger the radius, obviously the outermost electrons are controlled by the smaller, easier to lose.

That's just my experience when I was studying chemistry, and I think that's the case anyway.

I feel that chemistry is not entirely a science subject, there are things to memorize, and there are calculations like science, and the difficult problem is no less than a math problem.

The most important thing is to attend classes, you must be serious! Listen to the knowledge points taught by the teacher, as well as some extended knowledge. Of course, if you have limited energy, you can skip listening to those extracurricular knowledge, but I personally think that is very important.

The second point is the notes, and you should never copy them all down. Otherwise, your socks are not notes, but the teacher's textbook. As mentioned above, listening is the most important thing, and then write down what you feel is necessary.

There is also the need to collect the wrong questions that you feel necessary to write down in a book, and the question must be classic and representative, and you can review and read the wrong question book in the future, instead of turning over the previous exam papers and homework. (This method is still used in high school, and it is beneficial to learn in high school by forming a habit from junior high school.) ）

The third point is to read the teacher's lecture and the class again in general during the self-study class. This is important because, after reviewing it yourself, you can be more impressed.

In the end, it's homework, do it seriously, of course it's nonsense. Although the tactics of the sea of questions are not good, proper practice is the process of applying what you have learned in class.

That's basically it, don't be too stressed, mentality is very important, and a good attitude is also the key to learning various disciplines well.

Hope these are helpful to you. (I hit it myself, and I didn't copy it).
