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
`X^(3)` : [Ar] `3d^(5) = 23` electrons. Since `X^(3+)`
Ion is formed by the loss of 3 electrons . X will have 26 electrons. Therefore, atomic number of X is 26.
