Stars can make elements through nuclear fusion or neutron capture.


Elements are produced in different ways.
Hydrogen, Helium and traces of Lithium and Beryllium were made in the Big Bang.

Lithium, Beryllium and Boron can't be made in stars are they are by products of other fusion processes. These elements are made by cosmic rays colliding with Carbon and Oxygen atoms.

Most other elements up to Iron are made by fusion processes in stars.

Heavier elements are made by a neutron capture process in supernova explosions.
