Solution

Q.
The number of d-electrons in ${Fe}^{2 +} (Z = 26)$ is not equal to the number of electrons in which one of the following [2015]

1 d-electrons in Fe (Z = 26)

2 p-electrons in Ne (Z = 10)

3 s-electrons in Mg (Z = 12)

4 p-electrons in Cl (Z = 17)

Ans.
(4)

Number of d-electrons in ${Fe}^{2 +} = 6$

Number of $p$ -electrons in $Cl = 11$

Solution

Q. The number of d-electrons in Fe2+(Z=26) is not equal to the number of electrons in which one of the following [2015]

1 d-electrons in Fe (Z = 26)

2 p-electrons in Ne (Z = 10)

3 s-electrons in Mg (Z = 12)

4 p-electrons in Cl (Z = 17)

Ans. (4) Number of d-electrons in Fe2+=6 Number of p-electrons in Cl=11
