For each of the following ions, indicate the total # of protons and electrons in the ion

Co+2
Co+3
Cl-1
K+1
S-2
Sr+2
Al+3
P-3

The atomic number gives you the number of protons.

The atomic number minus the charge gives you the number of electrons. (For chloride, for example, it is 17 minus -1 or 18.)
