Hey there! I could help you out with your question.

°.✩┈┈┈┈∘*┈┈୨♡୧┈┈*∘┈┈┈┈✩.°

According to research it claims that "Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei. ... This is when recombination occurred — neutral hydrogen (and helium) finally appeared because they could “recombine with” (hold on to) electrons without easily losing them to stray radiation."The Big Bang created the elements on the periodic table, building blocks that help make up the universe. ... In stars, hydrogen atoms fuse to create helium — the second most common element in the universe, according to Encyclopedia.com. Helium has two protons, two neutrons and two electrons. Hydrogen is known to be the first element in the periodic table of elements. It has one proton in its nucleus and one outter electron. It is a very light gas and also flammable. ... Its atomic symbol is H and its atomic number is one.
