2. Where were the elements made?
There are 92 naturally-occurring elements and about 15
artificially-produced elements.
Elements were originally made in
stars. In the early stages of a star’s
life, light elements, such as
hydrogen and helium, are formed.
These fused together to make
heavier elements such as carbon.

Some of the even heavier elements
were produced deep within stars
and were sent out into the Universe
when the stars exploded.

Most of the artificially-produced elements have only been
made in nuclear reactors or particle accelerators.
