How do find the number of electrons, protons, and neutrons given a specific element?
Got a Periodic Table.........

The number of neutrons is a bit more problematic inasmuch as a given element can several isotopic forms. For sulfur, oxygen, and hydrogen we choose the COMMON isotopes,
ARE you happy with this?
