Helium
Berrylium
Fusion of two hydrogen nuclei results in the formation of helium and a stray neutron. H31 + H21 -----> He42 + n10 The hydrogen with atomic number 3 is trituim and the hydrogen with atomic no. 2 is deutrium. They both fuse together to form Helium with the release of a spray neutron, accompanied by a large release of energy.
Hydrogen-1 and hydrogen-2 are alike in that they both have one proton in the nuclei of their atoms.
The sun (mostly hydrogen) is basically a nuclear fusion reactor, releasing energy by nuclear fusion of hydrogen nuclei into higher elements (which is where the higher elements actually come from). In fact it is a fusion bomb held together by stupendous gravity. No hydrogen, no sun, no people.

Hydrogen nuclei, which are protons
Nuclear fusion occurs when two nuclei fuse together. This is frequently nuclei of deuterium and tritium (both hydrogen isotopes), which form a helium nucleus plus a neutron.
Two atoms bonded together
Hydrogen nuclei (protons) fuse together and produce helium nuclei
Scientists reckon that Hydrogen nuclei were the first to form (being the most simple element), around a few milliseconds after the `big bang`. Between 3 and 20 minutes they reckon that helium nuclei were the next to be formed. They then say that these nuclei were not able to capture electrons until around 379,000 years later.

Two atoms bonded together
Joining two nuclei to produce an atom of a different element is called fusion.
Only when the nuclei of the element contain no neutrons. This occurs naturally only for hydrogen-1.
hydrogen nuclei join together to make a larger helium.
Element number 99, later named Einsteinium, was discovered in the debris from the first hydrogen bomb explosion in 1952. Only a tiny number of atoms were detected, formed from the decay of neutron-bombarded californium nuclei.
