Big Bang• Hydrogen and a small amount of Helium

formed.• Hydrogen has 1 Proton in its nucleus, Helium

has 2 protons.

Fusion!

• Happens in stars• Elements are created through forcing atoms

together into larger atoms – This also releases the energy that makes stars bright.

• In the biggest stars (millions of times bigger than the sun) elements as heavy as Iron (26 protons) can be formed

Supernova

• When large stars fuse all of their atoms into Iron, they cannot fuse more, become unstable, and explode.

• This intense explosion causes atoms to fuse into even larger atoms - all the other heavy elements.

Our Solar system• Our sun and planets were made from a nebula

that was formed out of leftovers from supernovas.

• This is why we have so many different elements on Earth.
