Helium is a completely unreactive element because it has a full outer electron shell, making it very stable and unlikely to gain or lose electrons to form compounds with other elements. Additionally, its small atomic size and lack of available orbitals for bonding further contribute to its inert nature.

Why is helium non-reactive?
Helium is nonreactive because of its full outer shell of electrons and forms no compounds.
Is helium a reactive molecule?
No, helium is a noble gas and is known for its inert and non-reactive nature. It is a colorless, odorless, and tasteless gas that does not readily form compounds with other elements.
What element is nonreactive and discovered as a pure element?
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.
What is the least active of the following nonmetals is helium carbon chlorine or oxygen?
Helium is the least reactive element, to the point of being unreactive.
Which is more unreactive helium or krypton?
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.
Why are there no compounds at all with helium in them?
Because helium is an unreactive chemical element.
What is an element that is unreactive odorless and colorless?
helium
Why does not hydrogen combine with helium?
Helium has completely filled orbitals and hence is unreactive.
What is the safest element?
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.
What element that is considered unreactive because it has a filled outer energy level is?
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.
Why is helium non-reactive?
Helium is nonreactive because of its full outer shell of electrons and forms no compounds.
Is helium a reactive molecule?
No, helium is a noble gas and is known for its inert and non-reactive nature. It is a colorless, odorless, and tasteless gas that does not readily form compounds with other elements.
What element is inert?
Some element that is unreactive, like any of the rare gases helium, neon, argon etc.
What is element is an unreactive gaseous element that is a product of the nuclear reaction of hydrogen atoms?
Balls
How does helium react with other substances?
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.
What is the least active of the following nonmetals is helium carbon chlorine or oxygen?
Helium is the least reactive element, to the point of being unreactive.
Which is more unreactive helium or krypton?
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.
