The quantum numbers of four electrons are given below: I. II. III. IV. The correct decreasing order of energy of these electrons is IV > II > III > I I > III > II > IV III > I > II > IV I > II > III > IV
Multiple Choice Options
- A IV > > II > > III > > I
- B I > > III > > II > > IV
- C III > > I > > II > > IV
- D I > > II > > III > > IV
Step-by-Step Verified Solution
(I) n = 4 , I = 2 , m I = _ 2 , s = _ 1 2 ; represents 4 d ( n + I = 6 )
(II) n = 3 , I = 2 , m I = 1 , s = + 1 2 ; represents 3 d ( n + I = 5 )
(III) n = 4 , I = 1 , m I = 0 , s = + 1 2 ; represents 4 p ( n + I = 5 )
(IV) n = 3 , I = 1 , m 1 = _ 1 , s = + 1 2 ; represents 3 p ( n + I = 4 )
Order of energy depends on the ( n + I ) , greater is the ( n + I ) value greater is the energy, if ( n + I ) is same, then it depends on n n ; if ' n ' is more, energy is more.
Step-1: According to ( n + I )
Energy = ( I ) > ( II ) = ( III ) > ( IV)
Step-2 : If n _ , then energy increases
Energy = (I) > (III) > (II) > (IV)
