1.	If there are 13 electrons in M shell and 1 electron in N shell th en the num ber of unpaired electrons in such atom will be.....
Answer» 5 4 3 6 Solution :K shell `therefore`n = 1 L shell `therefore`n = 2 M shell, n = 3 an d 13 electrons in it `therefore 3S^(2) 3p^(6) 3D^(5)`configuration N shell `therefore`n = 4 and 1 electron in it`therefore``4S^(1)` configuration This configuration `3s^(2) 3p^(6) 3d^(5) 4s^(1)`is of CR as below `therefore`Six unpaired electrons are p RESEN t in this
