.In absence of Pauli exclusion principle, theelectronic configuration

1.	.In absence of Pauli exclusion principle, theelectronic configuration of Li in ground siatemay be:(a) 1s2, 2s(b) 1s3
Answer» The electronic configuration 1s3is prohibited by thePauliexclusion principle, which is stated simply as: No individual orbital may be occupied by more than two electrons, and if two electrons do occupy a single orbital, then their spins must be paired. option-b
