This is a nuclear change. The atoms change into helium atoms. The loss of mass in the change convert to energy, thousands of times the amount of energy of a chemical change.
Fusion experiments and designs for fusion reactors generally focus on hydrogen, in the forms of deuterium (hydrogen-2) and/or tritium (hydrogen-3). It should be born in mind that there is not much preventing any atom of any natural element undergoing fusion with something else. In fact, virtually all of what is around us is either hydrogen or something made by fusion, and this includes all the heavy elements like lead uranium.
The sun's energy comes from a process called nuclear fusion. In the sun's core, hydrogen atoms fuse together to form helium, releasing vast amounts of energy in the process. This is what powers the sun and provides energy to sustain life on Earth.
At the instant of detonation, the temperature at the core of the fusion reaction is high enough for the fusion of deuterium with tritium, and of tritium with tritium (50,000,000°C and 400,000,000°C, respectively.
The sun's fusion rate remains relatively steady due to a balance between gravity compressing the core and the energy produced by nuclear fusion pushing outward. Variations in the fusion rate are minimal and occur over long timescales due to changes in the sun's internal conditions.
The sun shines because some of the nuclear energy is transformed into radiant energy. Enormous compression due to gravity and extremely high temperatures in the deep interior of the Sun fuse the nuclei of hydrogen atoms together to form helium nuclei. This is called thermonuclear fusion (a process that releases radiant energy, a small part of which reaches Earth).
Mostly hydrogen, helium is also present due to fusion.

its not perfectly round .It is because of continuous bombardment in plasma due to fusion of hydrogen and release of their energy.
It is just protons joining together, which are hydrogen ions, so the only fuel required is hydrogen, the reaction proceeds due to the high pressure at the sun's core, due to the immense gravitational compression. See the link below

Stars form when clouds of gas collapse, due to their own gravitation. They get their energy from nuclear fusion - mainly, converting hydrogen to helium.
Hydrogen and oxygen. On the sun two hydrogen atoms and one oxygen atom are fused at the core which keeps the suns light going and giving it more energy. The result of this is water. H2( hydrogen 2 ) O( oxygen ) h2o

The greatest amount of energy released is due to the fission (atomic bomb) or fusion (hydrogen bomb) reaction after the the weapon is detonated by one of several means (gun-type trigger, implosion, or boost method). Fission reactions are responsible in most detonations for the greatest amount of energy released; this is due to the fact that hydrogen bombs (fusion) use fission explosions as a detonator, and that the fusion process can also cause further fission reactions.
The sun's fusion rate remains relatively steady due to a balance between gravity compressing the core and the energy produced by nuclear fusion pushing outward. Variations in the fusion rate are minimal and occur over long timescales due to changes in the sun's internal conditions.
When a star exhausts its core hydrogen, nuclear fusion in the core stops, causing the core to contract and the outer layers to expand and cool, making the star grow larger. The increase in size is due to the star transitioning into the red giant phase as it starts burning hydrogen in a shell surrounding the core.
