The periodic table is divided into different blocks. elements that have complete valence electron shells are mostly found in s block. d block. p block. f block.

P Block

Explanation:

The p block elements involve group III A, IV A, V A, VI A , VII A and VIII A. But among these groups, there are only Nobel gases that have complete valence shell electrons.The Nobel gases have their complete valence shell electrons due to which they are least reactive and stable one. They are found in VIIIA group of the periodic table at right side.

The correct answer is c
