What is produced by primordial nucleosynthesis?

Answer 1

Primordial nucleosynthesis produced some of the lighter elements.

Primordial nucleosynthesis, sometimes referred to as Big Bang nucleosynthesis, is believed to have taken place in the first 20 minutes following the Big Bang. Prior to the Big Bang, only hydrogen was known to exist. During nucleosynthesis, helium-4 was the principal element produced, with smaller amounts of deuterium, helium-3, lithium, and beryllium also being produced.

Stars produced all elements heavier than beryllium much later.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
