Question

Imagine a Universe in which the four quantum numbers can have the same possible value as in out Universe except that the magnetic quantum number (m) can have integral values from 0 to+-(L+1). Find the electronic configuration ofatomic number 20.

Answer 1

Answer:

1s6, 2s6 , 2p8

Explanation:

The new magnetic quantum number have values 0+_(l+1). Therefore for s subshell l=0. Therefore it's values of Magnetic quantum number is -1,0,+1. Therefore it has 3 orbitals it's spin has values +_ 1/2, hence it can contain 6 electrons. Similarly in p we have 5 orbitals, therefore it can have 10 electrons in it. Now according to aufbau, pauli, hund's rule it's electronic configuration is 1s6, 2s6 , 2p8
