(a)
Interpretation:
To determine the number of proton and electron of the ionic species Mg2+.
Concept Introduction:
Ions are formed by loss or gain of an electron. If an atom gain the electron it will carry positive charge and if it lose the electron it will carry the positive charge. The electron present in the outermost shell of an atom is mostly responsible for formation of ions. If the number of proton is less than number of electron the species is anionic and if the number of proton is higher than number of electron the species if cationic.
