Hydrogen gas is H2
The formula for magnesium and hydrogen gas is Mg and H2 respectfully.
The chemical formula for Hydrogen gas is H2
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
Hydrogen is a diatomic element, so the formula would be H2.The chemical symbol is H, but hydrogen usually appears as H2.
Formula: H2
There is no structure for hydrogen gas because particles in a gas roam freely.
2: As a gas the molecules of hydrogen have the formula H2.
Assuming that you mean Hydrogen, its formula is H2, hydrogen is diatomic molecule
Its H2
