Why are the noble gases sometimes called the inert gases?

Answer 1

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

Answer 2

Noble gases are called inert gases because they were originally thought to be chemically inert or unreactive due to their full outer electron shell, which makes them stable. However, some noble gases can form compounds under certain conditions, challenging this idea of complete inertness.

Answer 3

Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).

Answer 4

because they were thought to be completely unreactive.In 1962 chemists got xenon to react making a compound known as XePtF6

Answer 5

The noble gases were once called inert gases because they were thought to be completely unreactive .

Answer 6

Some inert gases are NO, CO, N2o which are not noble.
