Question

is it possible to have 1s^3 configuration or not?​

Answer 1

Explanation:

No. The 1S3 configuration is forbidden by a fundamental feature of nature summarized by the Austrian physicist Wolfgang Pauli in the Pauli exclusion principle. After filling 2 electrons in 1S orbital, remaining electrons are assigned to the next coming orbitals...

Answer 2

Answer:

No

Explanation:

s refers to an L value of 0. No. of orbitals possible is given by 2(L)+1, so for an s subshell, its 2(0)+1 which is 1. Each orbital can hold a maximum of 2 electrons, so 1s3 configuration is not possible. Only possibilities for 1s are 1s1 and 1s2

Hope this helps!
