Question

why helium is a inert gas

Answer 1

helium is a inert gas because it is very stable and doesn't react with other chemical elements

Answer 2

hi mate,

==>>because Heliums shell that is full with only two electrons.

==>>The fact that their outer shells are full means they are quite happy and don't need to react with other elements.

==>>In fact, they rarely combine with other elements. That non-reactivity is why they are called inert.

noble gases

==>>Helium is a colorless, tasteless and odorless gas.

==>>Helium is the second most common element in the Universe (after hydrogen), making up around 24% of its mass.

==>>Helium is part of a group of chemical elements called noble gases, the other five that occur naturally are neon, argon, krypton, xenon and radon.

==>>Characteristics: Helium is a light, odorless, colorless, inert, monatomic gas. It can form diatomic molecules, but only weakly and at temperatures close to absolute zero.

==>> Helium has the lowest melting point of any element and its boiling point is close to absolute zero.
