If the electronic configuration of an element is1s^(2) 2s^(2)2p^(6) 3s

1.	If the electronic configuration of an element is1s^(2) 2s^(2)2p^(6) 3s^(2) 3p^(6)3d^(2) 4s^(2)thefour electrons involved in chemical bond formation will be………….. .
Answer» `3p^(6)` `3p^(6), 4S^(2)` `3p^(6), 3d^(2)` `3d^(2) , 4s^(2)` SOLUTION :In transition elements ,i.e. d-block elements , electrons of ns ans (n-1) d subshells take PART in bond FORMATION.
