The number of protons uniquely identifes an element at all times, with no exceptions.
Helium always has two protons.
No the hydrogen nucleus is a proton. The helium nucleus is an alpha particle.
The helium nucleus is larger than the proton. The He nucleus consists of two protons, and one (rarely) or two (most commonly) neutrons. (These are He-3 and He-4, respectively.) That would make the helium nucleus a multiple of three or four times the mass of that of a single proton.
The gas is helium. Helium is inert and has 2 protons, while hydrogen has 1 proton.
The proton-proton chain is the name given to one common fusion reaction occurring in stars by which hydrogen is converted to helium, along with the release of energy.

They differ by the number of protons. Helium has 1 proton, helium has 2 proton.

A single proton was most likely removed from the helium atom to result in an atom of hydrogen. Helium typically has two protons, so removing one proton would leave one, transforming it into hydrogen, which has one proton.
An element with 1 proton is hydrogen. An Isotope called Tritium has one Proton and two Neutrons. Hope this helps.
By definition, a proton is positive, so a proton will always have a positive charge.
A proton and 2 neutrons.
This isotope of helium is helium-3; the atomic number of helium is 2.
helium with 2 proton Hydrogen has 1 proton.
