Question

question 16 of 25 which family contains elements with a full octet of valence electrons? a. the alkali metals b. the noble gases c. the actinides d. the halogens

Explanation:

Noble gases have a stable electron - configuration with a full octet (except helium which has a full duet) of valence electrons, making them chemically inert under normal conditions. Alkali metals have 1 valence electron, actinides are radioactive metals with complex electron configurations, and halogens have 7 valence electrons.

Answer:

B. The noble gases
