Question

If MG 2 + has 12 protons and 12 Neutron what is it atomic number and mass number

Answer 1

Explanation:

Atomic number of any element is equal to protons present in atom. Hence atomic number = number of protons= 12 Atomic mass is sum of protons and neutrons present in atom. Therefore mass number = number of protons (p) + number of neutrons (n) = 12 + 12 = 24
