What is the charge of an electron? - Answers- -
Atomic number - Answers- the # of protons
Element - Answers- are substances that cannot be broken down into simpler
substances by ordinary chemical reactions.
Isotope - Answers- form of an atom w/ a specific # of neutrons.
Atomic weight (Atomic Mass) - Answers- is the #that indicates how much matter that
atom contains compared w/ another atom. (# of P+) + (# of N) = atomic mass units
