Q1

The quantum numbers of four electrons are given below

I. \(n=4 ; l=2 ; m_l=-2 ; s=-\frac{1}{2}\)
II. \(n=3 ; l=2 ; m_l=1 ; s=+\frac{1}{2}\)
III. \(n=4 ; l=1 ; m_l=0 ; s=+\frac{1}{2}\)
IV. \(n=3 ; l=1 ; m_l=-1 ; s=+\frac{1}{2}\)

The correct decreasing order of energy of these electrons is

[Re-NEET 2024]

a

IV \(>\) II \(>\) III \(>\) I

b

I \(>\) III \(>\) II \(>\) IV

c

III \(>\) I \(>\) II \(>\) IV

d

I \(>\) II \(>\) III \(>\) IV
