Question

Quizplus · Accepted Answer

The Big Bang primarily formed hydrogen and helium, with trace amounts of lithium and beryllium. It is only through the processes of fusion in stars and supernova explosions that heavier elements are formed. Therefore, the Big Bang did not form all elements up to iron or all elements found in nature now. According to current scientific understanding, the Big Bang primarily formed hydrogen and helium. Other elements were formed later through processes such as nuclear fusion in stars and supernova explosions. However, the Big Bang did not form all elements found in nature as heavier elements were formed through later processes.
