Answer 2

Answer:

The word octet refers to the number eight, and the word duplet is related to “doublet” and refers to a pair or to the number two. Noble gases (or inert gases) such as neon (Ne) and argon (Ar) have eight electrons in their valence (outermost) shells, which gives them a stable electronic configuration.
