Hydrogen, then Helium, ect


Hydrogen is the most abundant because it is the simplest element. Hydrogen consists of 1 proton and 1 electron in the S-orbital. After the Big Bang when protons and electrons became associated, this was the first to be produced. Helium is the next simplest element consisting of 2 electrons 1 proton and 1 neutron.
