Which group on the periodic table would have zero electronegativity because they have a full octet?

inert or noble gases
alkaline earth metals

halogens

The group on the periodic table that would have 0 electronegativity due to the fact that their valence shell is full, i.e, have a full octet would be the inert or noble gases. They have a total of 8 electrons in their valence shell and are thus inert and cannot strongly attract electrons toward itself, from neighbouring atom electrons as it does not need to.

The answer is solid copper
