Why are the inert gases termed #"zerovalent"#?

Answer:

Because generally they do not form chemical compounds.

Explanation:

Traditionally, valence was defined as the number of hydrogen atoms that could bond to a particular element. Inert gases tend to form compounds with only the most reactive and oxidizing elements, namely oxygen and fluorine.

The electronic structure of the inert gases, which feature a full valence shell of electrons, can rationalize their poor reactivity.
