How should I study chemistry in junior high school? Be efficient, not rigid.

In the liberal arts of science, you must remember the basic knowledge first: the periodic table, basic chemical properties, etc., these are the words of chemistry, the basic language of chemistry, secondly, you must think carefully, be good at summarizing and classifying, and finally you must find out the rules, especially pay attention to the details.

Chemistry is an exploratory science, known as the liberal arts in science, the first to start learning must remember the basic knowledge: the periodic table, the basic chemical properties, etc., these are the words of chemistry, the basic language of describing chemistry, secondly, to think carefully, good at summarizing and classifying, and finally to find out the law, especially pay attention to the details.

Hope it helps!

It is necessary to listen carefully in class and take good notes, but you don't need to memorize them, turn through your notes every day before class, glance at equations when you have nothing to do, master types, and chemical symbols, and so on, and be sure to memorize them. The rest is nothing else I never memorized when I was in junior high school It's all okay to think about it I won't just look at it and recite it a few times over time It will be In fact, junior high school chemistry is nothing difficult The main thing is equations and experiments Just master it I studied this way The chemistry score of 79 in the middle school exam the year before last,,I don't know if it's suitable for you. You can try.

Really understand and understand the knowledge of the book, and then practice the most questions, for those who can't and do wrong, be sure to figure it out, and accumulate key points for review.

I'm sure I'll learn chemistry well.

Junior high school chemistry is so easy! Just those few chemical formulas, practice makes perfect, everything changes, remember the chemical formula, and understand the principle.

Memorize the definitions and understand them so that you can use them flexibly. Only by having imagination can we better memorize chemical formulas.

First of all, memorize the formula, memorize some steps, and find the teacher to figure out what you don't understand.

Memorize chemical equations and chemical formulas, as well as those concepts, and make sure that you are above 45.

Listen carefully in class, practice more and watch more

Memorize definitions, comprehension, and will not ask the teacher.

Let the teachers of our school give you make-up lessons.

Chemistry is an experimental discipline and a symbolic language discipline, which requires a lot of content to memorize, and the following points are the key to learning chemistry well:1Work on the basic concepts and memorize the basic concepts --- material changes (physical changes:

tristate change, deliquescent; Chemical changes. Chemical reactions: four basic types of reactions, chemical reactions, decomposition reactions, displacement reactions, metathesis reactions), properties (physical properties:

solubility, solubility, water absorption; Chemical Properties: Flammability, Oxidation, Reducibility, Stability, Dehydration), Substance Classification: (Mixtures, Pure Substances:

elemental, compounds: oxides, acids, bases, salts), solutions (solvents, solutes, homogeneity, stability, saturated solutions, unsaturated solutions, solubility, solute mass fraction); Composition and structure of matter: elements, atoms, molecules, ions, elemental valency, allotropes, allotropes; Relative atomic mass, element symbols, chemical formulas, relative molecular mass, and the law of conservation of mass basically cover the basic concepts of junior high chemistry.

2.Familiar with chemical terms: element symbols, ion symbols, schematic diagram of atomic structure, schematic diagram of ionic structure, chemical formula (familiar with the valency of common elements:

Monovalent potassium hydrogen chloride, sodium silver, divalent oxygen, calcium barium, magnesium, zinc, 12 copper, 23 iron, 3 aluminum, 4 silicon, 5 nitrogen and phosphorus, 246 sulfur, 2467 manganese), chemical equations. 3.Chemical Calculations:

Chemical formula calculation (elemental mass ratio. Calculation of chemical formulas, mass fraction of elements in compounds, mass fraction of elements in mixtures), calculation of chemical equations, calculation of solutions. The above three parts basically cover most of the content of junior high school chemistry, and when learning, you will take the foundation by doing questions (that is, what knowledge you use to do the questions, you will go back and make up what knowledge.

After a period of reinforcement (the premise is: you have to put in 100% effort, believe 100% meaning you should know: empty your mind and go all out), I believe that your chemistry score will improve to a certain extent.

Listen carefully to the teacher's lectures during class time, do questions carefully after class, memorize the chemical periodic table and formulas, and concepts, ask more, read more, and think more.

The learning methods of science are almost the same, I understand and memorize all the defining theorems, memorize the periodic table, understand and memorize various reactions, and then do more exercises and master them proficiently.

How do you learn chemistry well? You have to study hard, study hard, and he will learn chemistry well.

If you want to learn junior high school chemistry well, you must first develop good study habits and correct learning attitude, and be able to consolidate and review all the content of the chemistry exam after class, and try to maintain the same level as the teacher, and do not put today's chemistry knowledge into tomorrow's learning. Every day after class, I have to write down the physics problems I don't know, and then ask the chemistry teacher tomorrow. In this way, it will be helpful to learn junior high school chemistry well.

If you want to learn junior high school chemistry well, don't use inertial learning thinking to learn, many students use mathematical methods to learn junior high school chemistry, which ultimately leads to unsatisfactory junior high school chemistry results, and always makes mistakes where they shouldn't make mistakes. There is still a certain difference between the study of junior high school chemistry and mathematics, for example, some experiments in junior high school chemistry are still more practical, you just need to think about it. When learning junior high school chemistry, we should not only stay on the surface knowledge points of junior high school chemistry, but also learn to have a deep understanding of junior high school chemistry knowledge points and use certain chemical laws to learn junior high school chemistry.

Chemistry is a liberal arts subject in the sciences, which means that there is more content to memorize. It is also a relatively easy subject to learn well in science. To learn chemistry well, the first thing is to memorize, and it is important to memorize understanding, such as concepts, formulas, chemical elements, and the chemical properties of elements or substances.

Second, conscientiously study and master the content of textbooks. Thirdly, it is very important to do a good job in chemical experiments, pay attention to the phenomenon of the experiment, remember the causes and final results, and be proficient in the steps and precautions of the experiment. Fourth, listen carefully, take good notes, and remember the key content.

Fifth, do a good job of homework, and it is best to ask a few more whys in order to consolidate. It is very easy to do the above points well and learn chemistry well.

1.Be diligent in previewing, be good at listening to lectures, take notes, and try to do an after-class practice.

2.Review often, memorize more, review in time after class, and do homework carefully.

3.Thoroughly understand the textbook, connect with the reality, and carefully study the textbook with the textbook as the main line.

4.Pay attention to experiments, cultivate interest, and carefully observe the teacher's demonstration experiments.
