Consider value of all four quantum number of last electrons and magnetic moment and valence electrons of elements W, X, Y and Z in their ground state :

Element	$n$	$l$	$m$	$s$	Magnetic moment ( $\mu$ )	Valence electrons
W	3	0	0	$+\frac{1}{2}$	0	2
X	3	1	+1	$-\frac{1}{2}$	$\sqrt{3}$	3
Y	3	1	-1	$+\frac{1}{2}$	$\sqrt{15}$	5
Z	3	1	0	$-\frac{1}{2}$	$\sqrt{8}$	6

Then according to given information the correct statement(s) is/are : (1) I.E.₁ of element W is greater than I.E.₁ of element X (2) I.E.₁ of element Y is greater than I.E.₁ of element Z (3) I.E.₂ of element X is greater than I.E.₂ of element W (4) I.E.₂ of element Z is greater than I.E.₂ of element Y
