Question

2) Electronic configuration of a transition element X in +3 oxidation state is [Ar] 3d^5 .
The atomic number of the element is
a) 25
b)26
c) 27
d) 24​

Answer 1

The answer of your question is 24.

Answer 2

Atomic number of element is 26.

No. of electrons is = 23 + 3

EXPLANATION-

as element X had Ar + 5

but after oxidation which means removal of electron 3 electrons are removed so, remaining electrons

= X+3

so no. of electrons in X = 23 + 3 = 26

since,

no. of electrons = no. of protons = atomic number.

hence, atomic no. is 26
