The quark-gluon plasma that composes the universe cools until hadrons, including baryons such as protons and neutrons, can form. At approximately 1 second after the Big Bang neutrinos decouple and begin traveling freely through space. This cosmic neutrino background, while unlikely to ever be observed in detail, is analogous to the cosmic microwave background that was emitted much later. The majority of hadrons and anti-hadrons annihilate each other at the end of the hadron epoch, leaving leptons and anti-leptons dominating the mass of the universe. Approximately 10 seconds after the Big Bang the temperature of the universe falls to the point at which new lepton/anti-lepton pairs are no longer created and most leptons and anti-leptons are eliminated in annihilation reactions, leaving a small residue of leptons.

So, to summarize, matter and anti-matter condense out of the quark-gluon plasma, a cosmic neutrino background is created, most matter and anti-matter is annihilated.
What else can I help you with?
When did the first nucleosynthesis take place?
The first nucleosynthesis is thought to have occurred shortly after the Big Bang, where simple elements like hydrogen and helium were formed. This initial phase of nucleosynthesis laid the foundation for the creation of more complex elements in stars and supernovae over time.
Which chemical element was created first?
According to the Big Bang Theory or Creation, hydrogen was first then the heavier elements. Man has created a few artificially and Neptunium was the first of these. Generally speaking, elements are not created by man they are pre-existing.
What was the first two element existed seconds after the big bang?
Actually there is only one element that was formed shortly after the big bang and that is hydrogen. All the other elements were made either by nuclear reactions taking place in the core of burning stars, or by the catastrophic explosion called supernovas that are sometimes produced when stars die. - This is from a highly credible source (book)
How did the big bang theory form the sun?
Hmph. The Big Bang theory did not form the sun. The big bang formed the elements hydrogen, then hydrogen began to create helium. Then stars were formed out of these two elements and that is how our sun was created.
How is stellar nucleosynthesis different from big bang nucleosynthesis?
Stellar nucleosynthesis refers to the process by which elements are formed within stars through nuclear fusion during their lifecycles, primarily converting hydrogen into helium and heavier elements in later stages. In contrast, big bang nucleosynthesis occurred in the first few minutes after the Big Bang, resulting in the formation of the lightest elements, primarily hydrogen, helium, and trace amounts of lithium and beryllium. While stellar nucleosynthesis builds upon the elements formed during the big bang, it occurs under different conditions and leads to the creation of heavier elements over billions of years.
When was first element created?
The first elements were created shortly after the Big Bang, around 13.8 billion years ago. Hydrogen and helium were among the first elements formed in the early universe through nucleosynthesis.

Which element was created during the big bang?
Hydrogen and helium were the two main elements created in abundance during the Big Bang nucleosynthesis. These elements were formed in the first few minutes after the Big Bang, when the universe was hot and dense enough to support nuclear fusion.
After the Big Bag the abundance of elements heavier than helium was?
Even today, 14 billion years after the Big Bang, the most common element is still hydrogen. Shortly after the big bang, the abundance of elements heavier than helium would have been "very small, almost non-existent". Hydrogen, the simplest element, has one proton. Helium, the next most common, has TWO protons. The only other element that would have existed after the big bang but before the formation of stars might have been lithium, with an atomic number (number of protons) of 3.
What 2 elements started the big bang and everything in your universe?
No element "started" the big bang. The big band eventually produced mainly hydrogen and helium, which may be the answer you were looking for.

What is the important of the big bang?
It created the universe, it created all the elements we use and live with.
How did the big bang theory form the sun?
Hmph. The Big Bang theory did not form the sun. The big bang formed the elements hydrogen, then hydrogen began to create helium. Then stars were formed out of these two elements and that is how our sun was created.
