Bhavya
Sr+2 is diamagnetic.
The atomic number of Sr is 38.So we can write its Electronic configuration (E.C.) as :
Sr = [Kr]5s2
Now,when we have Sr+2 ion that means the new E.C. becomes
Sr+2 = [Kr] 5s0
Since Kr is noble gas hence there will be no unpaired electron and that’s why Sr+2 is diamagnetic.
