If the electronic configuration of an element is $$1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^2}4{s^2},$$ the four electrons involved in chemical bond formation will be _________.
A.
$$3{p^6}$$
B.
$$3{p^6},4{s^2}$$
C.
$$3{p^6},3{d^2}$$
D.
$$3{d^2},4{s^2}$$
Answer :
$$3{d^2},4{s^2}$$
Solution :
Electrons from outermost shells $$ns$$ and $$\left( {n - 1} \right)d$$ take part in bond formation for transition elements.
