the answer is simple it is that both elements have different masses which makes each formula different
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
Because hydrogen is lighter that helium
The symbol for hydrogen gas is H2
Hydrogen
Helium has replace hydrogen in airships

Because hydrogen is lighter that helium
helium and hydrogen...
helium is a noble gas
The symbol for hydrogen gas is H2
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
hydrogen and helium
they are hydrogen and helium .
Hydrogen was, and is, the lightest gas
The SUN does NOT BURN gas. It is a FUSION of hydrogen atoms into helium atoms.
Hydrogen
The gas that helium replaced was Hydrogen
