why does hydrogen has tyo complete its duplete and not a octatet
Asked by Harshita Bhola | 31st Oct, 2010, 12:00: AM
The duet rule states that complete filled first shelll stabilises the atom.Example is the noble gas helium which has two electrons in its outer shell, which is very stable. (Since there is no 1p subshell, 1s is followed immediately by 2s, and thus shell 1 can only have at most 2 valence electrons). Hydrogen only needs one additional electron to attain this stable configuration. So, hydrogen follows duet rule and not the octate rule.
We hope that clarifies your query.
