Explanation:
Detailed explanation-1: -Hydrogen and helium atoms emerged a measly 379, 000 years after the Big Bang. As the hot, dense plasma of protons, electrons and photons that was the universe began to cool and expand, electrons and protons gathered to form atoms.
Detailed explanation-2: -Hydrogen-with just one proton and one electron (it’s the only element without a neutron)-is the simplest element in the universe, which explains why it’s also the most abundant, Nyman said.
