The easiest way to distinguish them is by the combustion test. Hydrogen is flammable and will burn. You can also pass hydrogen, which is reactive, through various solutions and it will be combined, whereas helium will almost never chemically react.
I am unsure what you mean by the formula for Hydrogen and Helium because both are an element, not a compound and you would generally not have a formula for an element. However, I can tell you that the difference between the formula for Hydrogen gas and Helium gas if; Hydrogen gas: H2 H-H Helium gas: He Hope this helps
helium is the most reactive, you can tell this by the amount of protrons and neutrons in it as the reactions need these to take place and the more there are the more likely it is to react like with the alkali metals the most reactice has the most protrons and neutrons
In the core of stars, hydrogen atoms undergo nuclear fusion in a three-step process called the proton-proton chain. First, two hydrogen nuclei (protons) combine to form a deuterium nucleus. Then, another proton is added to create a helium-3 nucleus. Finally, two helium-3 nuclei combine to produce a helium-4 nucleus, releasing energy in the form of gamma rays.
Colorado is below Wyoming
your question is a bit hard to understand with the spelling, so i'm not sure what you're asking. but i cant tell you that the universe is mostly hydrogen, about 90% i believe. followed by helium at around 8% i think. then everything else. stars primarily burn hydrogen, followed by helium, and then heavier elements as they get older. but they spend most of their lives burning hydrogen, they only start forming other elements to burn as they die.

They differ by the number of protons. Helium has 1 proton, helium has 2 proton.
There is no difference between hydrogen sulfide and hydrogen sulphide. The term "sulfide" and "sulphide" both refer to the chemical compound H2S, also known as hydrogen sulfide. The difference in spelling is simply a matter of regional or historical variation.
Our star I can tell you more about, but Alas Until we can burn ourselves up in other stars (which are at least light years away at the closest) I can only tell you the Chemicals the sun uses. The sun is about 75% Hydrogen, and just about the rest is mostly Helium. Which there are so plentiful amounts that It can burn for a very long time, at least until there is no more fuel. O.o
If they are converting hydrogen to helium, then they are on the main sequence. This can be confirmed with a spectral analysis
how can you tell the difference between a tortoise and a turtle by shell in picture
Can you tell the difference between Vyvanse and Concerta in a drug test
Vending machines have laser scanners that can tell the difference between the bills.
you can tell the difference between right and wrong from the little voice inside your head
please tell me the difference between thickness
no but you can tell the difference by taste
No difference
