Question

Which one of the following statements is true for an atom that has full s and p orbitals in its outermost energy level?

A. It's highly reactive only with halogens.
B. It has a stable octet and is unreactive.
C. It's highly reactive only with alkali metals.
D. It can be combined with most elements.

Answer 1

B.

Step-by-step 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.

Answer 2

B. It has a stable octet and is unreactive.

Step-by-step 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
