Is the discovery of chemical elements a patent?

Chemistry is not only a discipline, but also a passport to the mysterious world. Have you ever wondered about those wonderful chemical reactions? Why can some substances change, while others can't? Chemistry is more like a logical adventure than just rote learning.

Explore the world of chemistry

Chemistry is a world full of mysteries, and exploring it requires us to discover, summarize and practice with our heart. It takes our efforts to master chemical equations, understand the periodic table of elements and explore the functional groups of organic compounds.

Understand the principles of chemistry

Don't think that the more chemical equations you have, the better! What is really important is to understand the principles behind them, learn to classify and compare them, and explore their laws.

Master chemistry "language"

Inorganic reaction and organic reaction have their own advantages, but as long as you master their "language", you can talk to them easily!

Unlock the chemical "curse"

Exothermic reaction, endothermic reaction, reversible reaction ... these are all "curses" in the chemical world, waiting for you to solve their mysteries!

Discover the miracle of organic reaction

Substitution, addition, redox in organic reactions ... each is a small miracle, waiting for you to discover and appreciate!

Bravely meet the challenge of chemistry

So, don't be afraid of chemistry, meet the challenge bravely and explore this mysterious world! I believe you can become a master of chemistry!
