1. hydrogen, helium, lithium. Hydrogen was definitely the first element to be formed, because of its simplicity, consisting of only a single proton and a single electron. Heavier elements formed only through fusion of the existing hydrogen, which means that it longer for progressively heavier elements to form. Helium and lithium are the second and third lightest elements, respecitvely, meaning they would be the next to form. In fact, the only element to form in Big Bang nucleosynthesis, apart from hydrogen, helium, and lithium, was a trace amount of beryllium. No oxygen or carbon was formed in the Big Bang, although a small amount of deuterium was. However, deuterium is not an element, but a form of hydrogen. In any event, this process ended three minutes after the Big Bang, after which all formation of heavier elements occurred through fusion in stars.

Initially there were no elements formed in the Big Band. For the early periods of time the Big Bang had not cooled enough to form the elements.
