Question

how many valence electrons are present in outermost shell of p block elements​

Answer 1

eight electrons

eight electronsMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.

Answer 2

Answer:

8

Explanation:

There are four blocks = [ S,P,D,F ]

There is formula for finding electrons in outermost shell=

2n^.

n means number of block

For first = 2n^

Therefore,2 ×1^ =2

For second =2n^.

2 ×2^ = 2× 4 = 8

And hence answer is proved.
