1. electronic configration of Mg= K(2),L(8),M(2)
no. of protons=no.of electron=atomic no.= 12
no of neutron+ no of proton= atomic mass
So, no. of netron =24-12=12
2.electronic configration of S =K(2),L(8),;M(6)
no .of proton =no of electron = atomic no=16
no .of neutron = atomic mass - no of proton= 32-16=16
no. of protons=no.of electron=atomic no.= 12
no of neutron+ no of proton= atomic mass
So, no. of netron =24-12=12
