The number at the top is the “-“ and shows us the number of “-“
Atomic number and shows us the number of protons and electrons
31
the number at the bottom is the “-“ and that shows us the number of “-“ by doing this equation;
Is the atomic Mass and shows us the number of neutrons by taking the Atomic number and subtracting the atomic mass
Neutrons = Atomic Mass - Atomic Number
