Imagine a Universe in which four quantum no. can have same possible value as in our universe except the magnetic quantum no. (m) can have integral values from 0 to ±( $ℓ + 1$ ). Find the electronic Confiruration of atomic no. 20.

Options:

Answer:

Solution:

For $m = 0$ to $\pm (l + 1)$

For $n = 1$ , $ℓ = 0$ , $m = - 1, 0, 1$

For $n = 2$ , $ℓ = 1$ , $m = - 2, - 1, 0, 1, 2$

For $n = 3$ , $ℓ = 2$ , $m = - 3, - 2, - 1, 0, 1, 2, 3$

Hence, the s subshell will have 3 orbital,

and p subshell will have 5 orbitals.

d subshell will have 7 orbitals.

The electronic configuration is $1 s^{6} 2 s^{6} 2 p^{8}$
