The electronic configuration of transition element "X", is +3, oxidation state is `[Ar]3d^(5)`. What is its atomic number?

A

25

B

26

C

27

D

24

Text Solution

Verified by Experts

The correct Answer is:
B
Electronic configuration of `X^(3+):[Ar]3d^5`
Electronic configuration of X will be : `[Ar]3d^54s^2`
Thus, atomic number of transition element is 26.
