Question

unit 5 l test 2526
which group on the periodic table is inert, and has a full octet?
noble gases
halogens
transition metals
alkaline earth metals

Explanation:

Noble gases have a full octet (eight electrons in their valence shell) and are inert (unreactive) because they have a stable electron configuration. Halogens have seven valence electrons and are reactive. Transition metals have variable valence electrons and are reactive. Alkaline earth metals have two valence electrons and are reactive.

Answer:

Noble Gases
