I'm not very good at chemistry. Oh, I understand the basics well enough, water is made of two hydrogen atoms and one oxygen atom, but once you get past the basics there is an endless profusion of chemical compounds and I quickly become lost. It's almost like the English language, you can stick words, or atoms, together in a limitless number of ways. If you use it every day, those combinations will become familiar to you, like the books you have read. But if you don't immerse yourself in this sea of arcane knowledge it will always be gibberish.
