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.

How is the formula for hydrogen different from the formula for helium?

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


Which is the most reactive between hydrogen and helium?

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


What is the 3 step process that occurs in the core of stars?

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.

When it comes to gow the earth was formed which statement follows the atmosphere was mainly hydrogen and helium?

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.

Which of these tell how helium is different from hydrogen?

They differ by the number of protons. Helium has 1 proton, helium has 2 proton.


What is difference between hydrogen sulfide and hydrogen sulphide?

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.


What are the two main gases that stars are made of?

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


How can you tell if stars in a visual binary are on the main sequence?

If they are converting hydrogen to helium, then they are on the main sequence. This can be confirmed with a spectral analysis
