What do you have to memorize in high school chemistry?

In fact, chemistry is very easy to learn, first of all, you should not be afraid of him, do not have a psychological burden, this is the first step to success. Secondly, you have to memorize a little thing (very little), memorize the periodic table of chemical elements (except for actinides and lanthanides, if you still find it difficult, then divide the paragroup elements into periodic and family (that is, horizontal and longitudinal back), compare the law of chemical property change with the periodic table, and use the image memory method when remembering other things (you can remember it if you think it is easy to remember, no matter how dirty the memory association is). Again, take note of the more special elements, such as:

Mercury is a liquid metal. Take note of the common metal activity: barium (upside down), potassium, calcium, sodium, magnesium, aluminum, zinc, iron, tin, lead, hydrogen, copper, mercury, silver, platinum (this helps with displacement reactions).

Finally, as for the principle you said, if you have more time, I suggest you take some time to read the chemistry (except for the small print part) carefully, I have a classmate who also had a poor chemistry score in the first year of high school, so I suggested that he take this method, and finally he became the top chemistry student in our class (of course, a little worse than me, hehe!). ）。Another thing is to pay more attention to summarizing the questions and try to cultivate your interest in chemistry.

Finally, I wish you an easy way to learn chemistry!!

Periodic table and related, some chemical equations, special elements, some reaction products color, characteristics.

I don't think there is anything to memorize deliberately, listen more in class, understand more down, the textbook must be thoroughly understood, to be able to make use of it, the things in the book are dead, the key is that you have to learn a kind of thinking embodied in the textbook, to be able to do the transfer of knowledge, and to do more questions to achieve this effect.

Reaction dissolution and precipitation formula.

There are so many things to remember, and it's almost like a language. But I don't have the flexibility of language, read notes, do questions, and return to textbooks.

First of all, the first point is that the answer is a liberal arts student, and I can only tell you about my experience in language, mathematics, English, politics, history and geography.

English words (very, very, very important) High-frequency phrases Advanced sentence patterns (used in writing).

High-frequency ancient poetry Literary common sense Composition materials (template sentence pattern + character examples, especially models of the times, moving Chinese characters, etc.).

Mathematics is to brush up on more questions, which formulas do not need to be "memorized", and we must learn to integrate and apply them flexibly.

The political teacher asked him to memorize whatever he wanted, because he would definitely be able to write in the exam.

History focuses on the causes, backgrounds, and influences the meaning of historical events, and there is also the need to learn to read the materials to do big questions, and the answers are all in it, and you can't copy it directly! Learn to summarize and transform concisely!

Geography is the most powerful subject in the liberal arts, and if you want to learn to understand, rote memorization will not really be able to memorize and it is easy to confuse. But it must still be memorized to make codes. Physical geography should memorize the formula of jet lag, the formula of the solar altitude angle, the atmospheric cycle, the water cycle, the forest, the wetland, the biology, etc., the human geography should memorize the population, the city, agriculture, industry, etc., and we must learn to compare, various differences in longitude and latitude, etc.

However, the exam basically can't touch the original questions, and the materials will be a headache (especially when you brush a lot of questions in the third year of high school), which is a great test of whether you can grasp the essence of the questions at once and contact the textbook.

High school doesn't mean that I can go well in my studies by memorizing what I should memorize, especially the proposition of the high school exam paper is very examining, he is a screening exam, so the questions that should be done, and the concepts that should be clarified are not missing at all.
