Web(Since there is no 1 p subshell, 1 s is followed immediately by 2 s, and thus shell 1 can only have at most 2 valence electrons). Hydrogen only needs one additional electron to attain this stable configuration, while lithium needs to lose one. WebThis leaves two electrons that cannot be used for bonding (otherwise nitrogen would have to share more than 8 electrons, which is impossible). In the ammonia molecule, these electrons are paired and unshared, meaning that they are not engaged in bonding. Such electron pairs are referred to as lone pairs, unshared electrons, or nonbonding electrons.
