Question

Magnetic moment of $T{i}^{x+}$ = Magnetic moment of $C{u}^{y+}$
What are x and y?

• A. 3,4
• B. 3,2
• C. 3,1
• D. 2,3

Answer 1

The correct option is B 3,2

Answer = 0

The total magnetic moment of a substance is the resultant of the magnetic moments of all individual electrons. The magnetic moment of paired electrons is mutually compensated. The effective magnetic moment of transition metal ion depends upon the number of unpaired electrons present in it.

The effective magnetic momnet is ${\mu }_{eff}=\sqrt{n(n+2)}$

Electronic configuration of $T{i}^{2+}=\left[Ar\right]3d^{2}4s^0$ Number of unpaired electrons$=2\Rightarrow {\mu }_{eff}=\sqrt{8}$

Electronic configuration of $C{u}^{2+}=\left[Ar\right]3d^{9}4s^0$ Number of unpaired electrons$=1\Rightarrow {\mu }_{eff}=\sqrt{3}$

Magnetic moment of $T{i}^{2+}\text{/}=$ magnetic moment of $C{u}^{2+}$
