Jaelyn Acevedo · Answer 1

B.

Explanation:

For example the element with configuration

1s2 2s2 2p6 which is Neon, an inert.

It has a stable 8 electrons in its outermost shell which makes it stable.

Sydney Daugherty · Answer 2

B. It has a stable octet and is unreactive.

Explanation:

s orbital contains 2 electrons and p contains 6. When the outermost energy level of an element has a total of 8 electrons we call it stable octet and it is unreactive. Therefore the answer is B
