Both are elements.
Hydrogen (symbol, H) belongs to group 1, has one proton and one electron and is highly reactive element. Hydrogen exists as a diatomic gas (H2).
Helium (symbol, He) belongs to group 8, has 2 protons and 2 electrons and is chemically inert as it has completely filled orbitals. Helium exists as mono atomic element.
Helium is the lighter gas but hydrogen is very flammable
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.
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
helium in a jar diff from helium atom
The difference between helium and deuterium in the aspect of its structures all boils down to the configurations of its subatomic particles. Helium has 2 protons and electrons and 2 neutrons whilst deuterium, an isotope of hydrogen, has 1 proton, electron and neutron.

Hydrogen has more lifting power than helium because it is lighter. This means that a given volume of hydrogen can lift more weight than the same volume of helium.
Helium has one more proton than hydrogen
All stars fuse hydrogen into helium - the slight difference in atomic weight between 4 hydrogen atoms and one helium atom, is given off as radiation.

In fuel cells the hydrogen is oxidised to water. In fusion 2 different isotopes of hydrogen (deuterium and tritium) fuse together to form helium.

The sun fuses hydrogen into helium. The mass of the resulting helium is not the same as the original hydrogen. The difference is energy.

Nuclear fusion, in which hydrogen-1 is fused into helium-4.
helium is not present
The difference between helium and deuterium in the aspect of its structures all boils down to the configurations of its subatomic particles. Helium has 2 protons and electrons and 2 neutrons whilst deuterium, an isotope of hydrogen, has 1 proton, electron and neutron.
