Hydrogen, helium, and a small amount of lithium.
If the BB is an accurate description of the early existence our Universe, then the ratio of hydrogen to helium to deuterium would be a certain value. The actual ratio matches the prediction of the BB quite well.
Three minutes after the Big Bang, the universe had cooled down enough for protons and neutrons to begin combining to form the first atomic nuclei, a process known as nucleosynthesis. This marks the beginning of the era of light nuclei formation in the early universe.
the theory states that atoms formed during the big bang (like right as the big bang happened) Protons and neutrons were allowed to form about one second after the Big Bang. Electrons joined to nuclei to form permanent atomic bonds about 377,000 years later.
The first types of particles produced by the Big Bang were quarks and leptons. Quarks combined to form protons and neutrons, while leptons included electrons and neutrinos. These fundamental particles emerged during the early moments of the universe as it cooled and expanded. Eventually, protons and neutrons formed atomic nuclei, leading to the creation of hydrogen and helium.
The three stages of the Big Bang are the primordial nucleosynthesis, the recombination era, and the cosmic microwave background radiation era. In primordial nucleosynthesis, the first nuclei formed; during the recombination era, hydrogen atoms formed; and in the cosmic microwave background radiation era, the Universe cooled down enough for light to travel freely.
The process is called nucleosynthesis. After the Big Bang, the nucleosynthesis process involved the fusion of hydrogen and helium nuclei to form elements like lithium, beryllium, and some trace amounts of heavier elements.
That refers to the formation of atomic nuclei during the first few minutes after the Big Bang.
Hydrogen was formed in the early universe, around 3 minutes after the Big Bang during a phase known as Big Bang nucleosynthesis. At that time, the extremely high temperatures and pressures allowed for the fusion of protons and neutrons to form hydrogen nuclei.

Hydrogen was formed in the early universe through a process called Big Bang nucleosynthesis, where protons and neutrons combined to form hydrogen nuclei. It is the most abundant element in the universe, created during the first few minutes after the Big Bang.
It was formed by the big bang but nobody knows how it was formed or what there was before the big bang
Scientists reckon that Hydrogen nuclei were the first to form (being the most simple element), around a few milliseconds after the `big bang`. Between 3 and 20 minutes they reckon that helium nuclei were the next to be formed. They then say that these nuclei were not able to capture electrons until around 379,000 years later.
Everything happened after the big bang.

A theory that the universe formed in a huge explosion
Within the context of elements, Hydrogen is the most basic building block of our universe. Good old number 1 on the periodic table. It's simple structure tells us that it would've been the first element to form after the big bang. However, we can't say that it formed instantly. In the earliest stages the Universe would've been too dense and too hot for the formation of Hydrogen. If you are looking for a magic number for an assignment or something, you should be safe saying that they formed within 5 seconds.
a huge blast.
