APEMAN Strategy
In order to determine the number of protons and electrons in an atom, remember three things are always equal in a NEUTRAL atom
Atomic # = Protons = Electrons
When trying to find the number of neutrons in an atom, you will use the following:
Mass # - Atomic # = Neutrons
7
APE
Atomic number = Protons = Electrons (APE)
A = 1
P = 1
E = 1
8
MAN
Mass number - Atomic number = Neutrons (MAN)
M = 1
A = 1
N = 0
