Find the volume of ._(12) Mg ^(24) nucleus (in m^(3) )

An atom contains electrons,protons and neutrons.If the mass of each neutrons is halved, and each electron is doubled,then the atomic mass of Mg_(12)^(24) , approximately get reduced by

Number of atoms in 12 g of ""_(12)^(24)Mg is equal to

What is its atomic number and valency?
