WebJan 25, 2024 · The presence of eight electrons in the valence shell of an atom imparts stability to that particular atom. To attain stability, atoms transfer or share electrons within themselves in such a way that they can satisfy the octet rule and attain noble gas configuration. The key characteristics exhibited by outer-shell electrons are as follows: Webthe sharing of two pairs of electrons. Consider an atom with four electrons in its outer shell. If that atom is covalently bound to three other atoms within a molecule, then it is: in a …
