helium is chemically inert and doesn't undergo combustion reaction
There is no word equation, except that helium will exist as liquid phase in liquid helium
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.
The glow of the splint is extinguished, because helium can not support the combustion reaction with oxygen from the atmosphere that produces the glow.
If the atom has a balanced electrical charge, then # of protons = # of electrons, so the atom has 2 protons (Helium). The vast majority of Helium atoms have 2 neutrons.
The amount of helium in a tank depends on how big the tank is (volume), the pressure of the helium and its temperature. It is calculated from the ideal gas equation with allowance for compressibility.

Being a noble gas, helium can't burn.
Hydrogen + intense heat and pressure --> Helium + energy release
6Li + 1n --> 7Li --> 3H + 4He Hyrogen-3 or tritium
If radon-210 undergoes alpha decay, it will produce the alpha particle (which is a helium-4 nucleus) and polonium-206. The equation looks like this: 86210Ra => 24He + 84206Po You'll note that in the balanced nuclear equation, the atomic numbers, which are the subscripts, balance on both sides of the equation (86 = 2 + 84). The atomic masses, which are the superscripts, also balance on both sides of the equation (210 = 4 + 206).
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.
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.
When radium-226 undergoes alpha decay, it becomes radon-222. We write the equation like this: 88226Ra => 24He + 86222Rn Here we see the alpha particle written as a helium-4 nucleus, which is, in point of fact, what it is. Notice that the numbers that are subscripted are equal on both sides of the equation, and the superscripted numbers are as well. They must balance for your equation to be correct.
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.
