It feels like everything is made up of small elements, and I can write it in chemical formulas.
-
I find it very interesting to learn about chemistry because you can see a different world.
-
When you first learn about chemical elements, it feels unfamiliar, but it can also be amazing, and it is a field that you don't know about.
-
Learning about chemical elements is actually quite interesting, but it is a bit troublesome in addition to memorizing things.
-
It's all kinds of elements and all kinds of properties they belong to, and I feel like it's troublesome to remember, but the chemical experiment is still very interesting.
-
Learning about chemical elements can be annoying, and sometimes you will be confused and unable to figure out what to do.
-
The feeling of learning chemical elements is a mess, and it is only after learning it that you understand its laws.
-
Chemical elements are an indispensable subject in junior high and high school, and chemistry is also closely related to human life.
-
If you have the experience of studying chemistry, you will feel that chemical elements are very difficult to learn, and you are very afraid of learning.
-
Hydrogen, oxygen atoms make up water molecules, and water is made up of water molecules. Iron is made up of iron atoms. I think this is very strange.。。 I can't say ** is wrong... Oxygen is made up of oxygen molecules...
-
It doesn't feel very troublesome, it is regular, it grabs the functional groups organically, and the ions are grasped inorganically.
-
It is very troublesome to know how to write, how to read, and to apply formulas.

Hello dear<>
Here, according to the questions you provided, the feeling of learning elemental chemistry is as follows: Studying elemental chemistry is a very important subject, which involves many substances in our daily life, such as water, air, metals, etc. Elemental chemistry requires a certain level of knowledge of mathematics and physics, as well as skills for safe operation in a chemistry laboratory.
In the process of learning, you may encounter some difficulties, such as understanding chemical equations, calculating chemical reactions, etc., but as long as you work hard, you will definitely be able to master it. Studying elemental chemistry also requires certain practical skills, such as conducting chemical experiments and preparing chemical compounds. This requires not only the support of instruments and equipment, but also the literacy of experimental operation skills and laboratory safety awareness.
Overall, learning elemental chemistry requires patience and perseverance, and requires continuous learning and practice. However, by mastering the knowledge and skills of elemental chemistry, we can better understand and interpret the chemical reactions that occur around us, bringing more convenience and innovation to our lives and work.
A chemical element is a general term for a class of atoms that have the same number of nuclear charges (the number of protons in the nucleus). From a philosophical point of view, elements are the result of a qualitative change caused by a quantitative change in the number of electrons in an atom. [1] >>>More
