Question

what is octer rule.what are the duplet and octer element

Answer 1

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.

Thank you

Answer 2

Answer:

octet rule means that the electronic configuration of the elements is complete with the 8 electrons in the valence

in duplet rule electronic configuration of the elements is also completed but with the 2 electrons in the valence shell.

octet element-neon

duplet element-helium
