Hydrogen is a very unique element. It really can't be classified with any others. However, due primarily to the fact that helium rarely bonds, hydrogen is probably closer to sodium.
Hydrogen is more like Helium as it is a gas and will combust in the presence of oxygen.Even though hydrogen is placed in the same group as all the reactive metals such as sodium and potassium, this is one exception where the properties hydrogen does not match the others in the same group.
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.

Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.

A hot air balloon doesn't contain helium or hydrogen.
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.
The approximate size of a sodium atom is about 0.186 nanometers (nm) in radius. Sodium is a relatively large atom compared to hydrogen or helium because it has more electrons and protons, leading to a larger atomic radius.
The atomic number of helium is one more than that of hydrogen. In both the elements, the electrons are filled in the 1s orbitals. Hydrogen has one electron, helium has two.
Hydrogen is extremely flammable and helium is safer.
