The Formation of the First Atoms/Elements

Here are a couple websites that describe the model of the atom. We were thinking of having the students create models of a hydrogen atom and the taking notes on how these were formed after the Big Bang started to cool down. First the quarks and electrons were formed, then the protons and neutrons were formed out of the quarks, and then the hydrogen, helium, and lithium atoms were formed. Hydrogen was formed with just one proton and one electron (the only element with no neutron), while helium has two protons, two neutrons, and two electrons.
