500
Describe the basic structure of an atom including the subatomic particles and their charges. Then explain how you find each of those amounts on the periodic table.
Protons-positive, neutrons- neutral, electrons-negative. Atomic number- is number of protons and electrons. Neutrons is the atomic mass minus the atomic number.
