Question

7.    The electrons identified by quantum numbers n and .            a) n = 4, = 1     b) n = 4, = 0    c) n = 3, = 2    d) n = 3, = 1 can be placed in order of increasing energy, from the lowest to the highest as     1) d< b < c < a    2) b < d < a < c    3) a < c < b < d    4) c < a < d < b​

Answer 1

Answer:

The electrons are filled in the increasing order of (n+l) value.

1.4+1=5

2.4+0=4

3.3+2=5

4.3+1=4

If (n+l) value is same for two different n and l value, then electron first fills in the orbital in which the n value is less.

The correct order is 4<2<3<1.
