*it has a filled valence shell
Helium is nonreactive because of its full outer shell of electrons and forms no compounds.
No. Helium is not molecular it is monoatomic. Helium is unreactive and forms no compounds.
Helium is a nonreactive element that was discovered as a pure element. It is a noble gas with a full outer electron shell, making it stable and unreactive with other elements.
Helium is the least reactive element, to the point of being unreactive.
Helium is more unreactive than krypton. Helium is a noble gas located in the first group of the periodic table, making it the least reactive element. Krypton, also a noble gas, is located in the same group but is slightly more reactive than helium.
Because helium is an unreactive chemical element.
helium
Helium has completely filled orbitals and hence is unreactive.
Most elements are completely stable and safe. However, the safest elements would be the most unreactive. So, in that sense, the Inert Gases (exc. Radon, which is radioactive) are probably the safest group of elements, as they are completely unreactive.
Helium is considered unreactive because it has a filled outer energy level with two electrons in its 1s orbital. This makes it very stable and unlikely to form chemical bonds with other elements.
Helium is nonreactive because of its full outer shell of electrons and forms no compounds.
Helium is an element, and it's name on the Periodic Table is He
Some element that is unreactive, like any of the rare gases helium, neon, argon etc.
No. Helium is not molecular it is monoatomic. Helium is unreactive and forms no compounds.

Helium does not react with other elements. It is a noble gas and has a full outer shell of electrons. Because it is not seeking to gain or lose any of its electrons, it will not react.
