Being a noble gas, helium can't burn.
For any combustion reaction O2 is required .
Helium has a full outer shell of electrons, meaning it is stable in its elemental form and does not form chemical bonds or participate in chemical reactions such as combustion.
Hydrogen
Carbon, Hydrogen and Oxygen For example the combustion of hydrocarbon, C2H4 + 3O2 --> 2CO2 + 2H2O
Oxygen is a required reactant in a combustion reaction - without oxygen, you do not have combustion. If you combine a hydrocarbon with oxygen and add heat, you will cause a combustion reaction that results in carbon dioxide and water being formed (provided there was complete combustion).
helium is chemically inert and doesn't undergo combustion reaction
No. Oxygen is required for combustion. Mercury is not involved.
No, oxygen is required for combustion to take place.
The vast majority of the energy output of the Sun is not produced by chemical combustion at all, but rather by nuclear fusion of hydrogen to helium.
Oxygen is the required gas that is necessary for combustion
For any combustion reaction O2 is required .
Helium has a full outer shell of electrons, meaning it is stable in its elemental form and does not form chemical bonds or participate in chemical reactions such as combustion.
Yes Helium is safer than Oxygen, in that it does not feed combustion the way Oxygen does. In fact, a high concentration of Helium will extinguish a fire. BUT … In a closed area, you can suffocate if the concentration of Helium in the air gets too high.

The glow of the splint is extinguished, because helium can not support the combustion reaction with oxygen from the atmosphere that produces the glow.
