The number of d-electrons in Fe^(2=) (Z = 26)is notequal to the number

1.	The number of d-electrons in Fe^(2=) (Z = 26)is notequal to the number p of electrons in which one of the following?
Answer» p-electronsinCl (Z= 17) d - electronsin FE (Z =26) p- electronsin Ne (Z =10) s- electronsin MTG (Z = 12) Solution :p-electronsinCl (Z= 17) `Fe^(2+) ` has 6 d-electrons. (Option - A) has 11 p - el electrons , which are not equal to six d-electrons in `Fe^(2-)`
