The noble gases (with the exception of helium which has a duplet of electrons) have a particularly stable outer shell configuration of eight (octet) electrons, ns2np6. The negative and positive ions are. The duplet rule explains why hydrogen readily forms covalent bonds. By sharing its single electron, hydrogen can achieve a stable duplet configuration, leading to the formation of countless organic and. The main difference between octet and duplet rule is that the octet rule states that atoms tend to gain, lose, or share electrons in a way that allows them to have a full outer shell with eight.
