Structure Of Atom

The quantum numbers of four electrons are given below :

I. \(n=4 ; I=2 ; m_1=-2 ; s=-\frac{1}{2}\)

II. \(n=3 ; I=2 ; m_1=1 ; s=+\frac{1}{2}\)

III. \(n=4 ; I=1 ; m_1=0 ; s=+\frac{1}{2}\)

IV. \(n=3 ; I=1 ; m_1=-1 ; s=+\frac{1}{2}\)

The correct decreasing order of energy of these electrons is
