Question

Valence electronic configuration transition element is
a.ns²(n-1)d¹⁰
b.ns²(n1)d
c.ns¹-²(n-1)d¹-¹⁰
d.ns²(n-1)d¹-¹⁰​

Answer 1

Answer:

(d) is the right answer.

Explanation:

d-Block elements consist of elements belonging to group 3 to group 12. They have valence electrons in the d-shell. Their outermost electronic configuration is (n−1)d 1−10 ns 0−2

. They exhibit transitional behavior between s and p-block elements. Thus, they are even called as Transition Elements.
