Answer 2

Answer:

The atomic number (Z) of magnesium atom = 12

For neutral atom, Number of protons (p) = Number of electrons (e) = atomic number (Z)

i.e Number of protons in the nucleus of Magnesium atom = 12

Now, for Mg

+2

number of electrons = 12 -2 = 10

and the number of protons remains the same i.e 12
