Big Bang nucleosynthesis produced no elements heavier than lithium.
To do that you need stars, which means waiting around for at least 200 billion years.
I have some basic understanding of how this is done, and I have also found some technical information that at this time I don't understand.
Can you point me to some good articles on the topic, or perhaps cover some more advanced materials yourself?
The abundance ratio was about seven protons for every neutron.
Before one neutron half-life passed nearly every neutron had paired up with a proton, and nearly every one of these pairs had paired up to form helium.
Almost all the hydrogen and helium present in the universe today (and some of the lithium) were created in the first three minutes after the big bang. There are no stable isotopes (of any element) having atomic masses 5 or 8. The triple-alpha process is not relevant in main sequence (normal) stars like the sun because their core temperatures are too low.
All of the other naturally occurring elements were created in stars. You need really massive stars for this — say 20 to 120 times the mass of the sun.
