(a). A transition metal cation x^(3+) has magnetic momen sqrt(35) BM. What is the atomic number of x^(3+)? (b). Select the coloured ion and the ion having maximum Magnetic moment (i). Fe^(2+) (ii). Cu^(+) (iii). Sc^(3+) and (iv) Mn^(2+).

(a). A transition metal cation x^(3+) has magnetic momen sqrt(35) BM.

1.	(a). A transition metal cation x^(3+) has magnetic momen sqrt(35) BM. What is the atomic number of x^(3+)? (b). Select the coloured ion and the ion having maximum Magnetic moment (i). Fe^(2+) (ii). Cu^(+) (iii). Sc^(3+) and (iv) Mn^(2+).
Answer» Solution : (a). 26, `._(26)Feto3d^(6)4s^(2)` `Fe^(3+)to3d^(5)4s^(0)` `mu=SQRT(N(n+2))=sqrt(5xx7)=sqrt(35)` (b). Both these ions will be coloured and magnetic moment of `MN^(2+)` will be greater.
