Question

which statement is true about the noble gases in terms of their chemical properties? they have a full valence shell and are mostly inert. they readily form bonds with other elements. they are highly reactive and form compounds easily. they are unstable and have incomplete electron shells.

Explanation:

Noble gases have a full valence shell of electrons. This gives them a stable electron - configuration, making them mostly inert and less likely to participate in chemical reactions.

Answer:

They have a full valence shell and are mostly inert.
