Electronic confriguration of a transition element X in +3 oxidation states 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+)" is " [Ar]3d^5`
It represents the total number of `e^(Θ)` and oxidation state.
Therefore, atomic number of `X = 18 + 5 + 3 = 26`
Hence, option (b) is correct.
