An element in +2 oxidation state has 24 electrons. The atomic number of the element and the number of unpaired electrons present in it respectively are

Options

A. 24,4
B. 26,4
C. 24,2
D. 26,5

Answer

(b)

Explanation

Given that an element contains `24e^(-)s` in +2 oxidation state i.e., it contains 26 `e^(-)`s in '0' oxidation state.
`therefore`Atomic number (Z)=26 (Iron, Fe)

`therefore `Number of unpaired `e^(-)`s is 4.
