Electronic configuration of a transition...

Electronic configuration 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
`[Ar] 3d^5: As X^(3+) ` is formed by the loss of 3 electrons , the configuration of element X is `[Ar] 3d^(6) 4s^2` .
Atomic number = 26
