for CH301 and CH302
Periodic Table is a valuable reference tool for the chemist. Not only are the values of atomic weight and number available but also the layout itself is very helpful in understanding the chemical behavior of the elements.
Learning the names and formulas of the common polyatomic ions is a great way to further advance your chemical knowledge. Make sure you memorize the formula, the charge, and the name of each ion. Many of the names are systematic and you can actually learn more chemistry by knowing the names.
