All halogens or group 17 elements.
any time there are as many electrons and protons and they fill each orbital optimally.
They all have a full set of valence electrons.
socks answer should be D
The valence electron shell of noble gases is full.
the elections with the highest energy are in an f sub level. your welcome :))
Noble gases have completely filled orbitals, are stable and chemically inert (non-reactive). So generally they will not form compounds.
Its when the all the shells in an atom are full with electrons Loading...
They are all members of the noble gas group (group 18).
Noble Gas Configurations
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration.
Noble gases have completely filled orbitals / electron energy shells. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.
nitrogen will get noble gas configuration by adding three more electrons.
