Average Atomic Mass (Mass # = Protons + Neutrons)
Atomic Number: The number of protons in every atom of an element(Can also represent the number of electrons in a neutral atom.)
Electron Configuration:The number of electrons in each energy level; add the numbers to get the total number of electrons.
Element Symbol: The letter(s) used to identify an element
Oxidation Numbers: Possible charges an atom of an element can have
