The electronic configuration of potassium (K) is 2,8,8,1 instedad of 2,8,9 through the M shell can accommodate up to 18 electron Explain.

Text Solution

Verified by Experts

M shell cannot have more than 8 electrons in case it happens to be outermost or valence shell in an atom therefore the correct elctronic configuration of the element potassium (K) is 2,8,1 .For details consult section 4.8
