Chemical symbol (not formula) of hydrogen is H and for helium is He.
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
the answer is simple it is that both elements have different masses which makes each formula different
Hydrogen and helium
The chemical symbol for helium is "He."
Hydrogen is H2. Helium is He.
Hydrogen and helium are the two most abundant elements in the universe.
Hydrogen and helium are formed in Sun.
Hydrogen is lighter than Helium.
mostly hydrogen and helium
No. Helium and Hydrogen are two different elements.
Hydrogen and helium. Mostly hydrogen.
No, helium is almost 4 times as heavy as hydrogen.
