Standard hydrogen has one proton and one electron. Standard helium has two protons, two electrons and two neutrons (so it's about four times as massive as hydrogen). Also, hydrogen has one positive chemical link, while helium has no chemical links (it's a noble gas, and therefore very inert).

Hydrogen has one proton; helium has two. Also, helium has its last (its _only_, actually) valence complete, so it cannot bond naturally with any other elements (which is why it is an inert, or noble, gas). Hydrogen doesn't, so it can. This helps to explain why helium makes good blimp filler material and hydrogen makes the Hindenburg.

Hydrogen is a substance where each atom only has one electron while helium has 2. Helium is also lighter than hydrogen.

Hydrogen is explosive.
Helium is inert.
Hydrogen has only one electron in its outer shell, and seeks
to gain a second by sharing with anyone who can lend it
another electron to achieve the magic number of fulfillment of
two electrons in the first ring of electrons. Helium has two
electrons in its outer ring and is quite content to sit there
and do nothing.
Hydrogen is very light.
Helium is heavier but still very light in comparison to other gases.
Hydrogen atoms have one proton in their nucleus. Atomic Number = 1.
Helium atoms have two protons in their nucleus. Atomic
Number = 2.
Hydrogen gas is normally diatomic (paired atoms) and it is
somewhat happy in the state of H2.
Early European blimps used hydrogen gas as their lifting force.
The explosive nature of hydrogen (flamability) worked to their disadvantage, however, and many hydrogen blimps went down in flames. Blimps seen often in the USA use Helium gas for lift and are fairly safe as conveyances. Both hydrogen and helium are significantly lighter than the air in our atmosphere which contains mostly nitrogen, oxygen, and carbon dioxide.

Hydrogen is a gas and so is Helium.But the chemical name is different,energy potentilal,atomic mass,atomic number,mass,charecteristics etc are the difference between Hydrogen and helium.

hydrogen consists of one electron and one proton. helium of two electrons and two protons. hydrogen is the element with the number 1, and helium nuber 2. simply: because of this they are two different elements, so they have different properties,...

About the same as the difference between lead and gold.
