Helium is chemically inert and does not combine with any other element (including thallium).
Helium is inert and doesn't react with any other elements.
The liquid helium would boil and evaporate.
That would happen after it loses a certain amount of helium.
the lighted splint would stop burning as Helium does not burn.
it would be cray.
The reaction in the sun which gives us energy involves helium. If helium didn't exist we would receive no energy and life wouldn't exist on the earth.
Nothing
Thallium is an element on the periodic table. It's atomic number is 81.Because it is an element, I don't understand what you mean by "its formula".The symbol for Thallium is Tl, so the formula would be Tl...If you want the formula for a compound with thallium, that's a different story.It is not a diatomic element, if that's what you meant.For more information on thallium, go tohttp://en.wikipedia.org/wiki/Thallium
Sulfur
Helium is an inert gas meaning that it will not combine with other elements or compounds. More specifically, chlorine will not bond with helium. But, if it did, as could happen in a supernova explosion, since chlorine is 17 on the periodic chart, and helium is 2, when they fuse they would create an atom of potassium which is 19.
Just like a fire is gradually cooling down,so the Sun is.Its hottest elements(hydrogen)become helium,which is COLDER
The student tried to hypothesize what would happen if the two chemicals were combined.
