X

' in their ground state is

n = 4

l = 1

m = 1

and

s = -\frac{1}{2}

and spin multiplicity of element '

X

' in their ground state is 4. Which of the following order is incorrect ? (1) Magnetic moment :

U > V > A

(2) Atomic radius :

E > X > T

(3) Ionisation energy :

R > X > B

(4) Stability :

F^{3+} < E^{3+} < X^{3+}
