Helium has completely filled orbitals and is hence chemically inert.
None. Helium has completely filled orbitals it is stable and chemically inert (non-reactive). So, helium exists as mono atomic and not as a diatomic species.
Both are noble gases, have completely filled valence orbitals and hence are stable and chemically inert.
Helium is nonreactive because of its full outer shell of electrons and forms no compounds.
The only significant chemical property of helium is that it does not undergo chemical reactions.
Helium has completely filled valence orbitals, is stable and chemically inert.
Helium has completely filled orbitals and is hence chemically inert.
helium has completely filled valence electrons. hence it are stable, chemically inert and do not form compounds.

Helium is nonreactive because of its full outer shell of electrons and forms no compounds.
The only significant chemical property of helium is that it does not undergo chemical reactions.
Helium has completely filled valence orbitals (and thus has stable electronic configuration). Hence is is chemically inert or inactive. In fact, helium doesn't react with any other element.
Noble gases (such as helium, neon, argon etc) have completely filled orbitals. They have stable electronic configuration. Hence they are chemically inert (or do not react with other elements).
Helium has completely filled orbitals, is stable, has small size and is chemically inert. It doesn't form bond with any other element.
Helium has completely filled orbitals and are stable and chemically inert (non-reactive). So generally it will not accept / gain / share electrons and wont form any compounds.
Helium exists as single atoms because it is a noble gas, therefore it has a full outer shell.
