Hey, I'm new to chemistry, what are the basic things I should know about this subject? I would really appreciate if someone would tell me the basic

Well the periodic table helps and math math is much needed in chem as much as I hate it hope this helps if you need anything else I can tell you in the comments

Explanation:

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
