hydrogen and helium
Helium is an element, so it is made of only one type of atom.
The sun produces energy by fusing hydrogen atoms into helium atoms. This is a nuclear fusion that occurs at the sun's core.
Hydrogen atoms fuse into helium.
Since hydrogen atoms in the sun are fused into helium atoms, the amount of helium is increasing and the amount of hydrogen is decreasing.
The hydrogen nucleus has a single proton. The helium nucleus has two protons and one or two neutrons.
two hydrogen atoms
Hydrogen and helium make about 98% of the atoms in the solar system !
helium atoms
The SUN does NOT BURN gas. It is a FUSION of hydrogen atoms into helium atoms.
