Since the atomic number of a substance is the total number of electrons present in it, i.e. 2 + 8 + 2 = 12 . So the atomic number of the element will be 12.
For your better understanding :Always remember that the sum of the electronic configuration of an element will be the atomic number of that substance. And the mass number will be the sum of protons and neutrons of that element .
