yes
No. helium is chemically inert
No, helium is not reactive because it is a noble gas and has a full outer electron shell, making it very stable. In contrast, argon is also a noble gas and is not reactive due to its full outer electron shell.
Hydrogen is the most chemically reactive among the elements listed. It readily reacts with other elements to form compounds, while helium, argon, and neon are inert gases and generally do not undergo chemical reactions under normal conditions.
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.
helium is non reactive.
Noble gases, such as helium, neon, and argon, are the least chemically reactive elements. They have a full outer shell of electrons, making them extremely stable and unlikely to form chemical bonds with other elements.
The only significant chemical property of helium is that it does not undergo chemical reactions.
Helium is nonreactive because of its full outer shell of electrons and forms no compounds.
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 does not have chemical properties similar to Br (bromine). Helium is a noble gas and is chemically inert, while bromine is a reactive nonmetal.
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.
No, helium is not required for combustion. Helium is an inert gas that is chemically non-reactive and does not support combustion. It is often used for filling balloons and airships due to its lightness and non-flammability.
