Question

Why does it take so much heat and pressure to create helium and other elements?

Answer 1

Every atom in the universe once existed in the form of hydrogen. Collisions between hydrogen atoms create larger elements, such as helium. It is difficult to overcome the strong proton-proton (+ vs. +) electrostatic repelling force without a great deal of heat and/or pressure. If it was known or possible under more mild conditions, we'd have nuclear fusion reactors producing cheap and safe energy (as opposed to those scary nuclear fission types).

Answer 2

ahhh okay thank you so much!! it makes sense. I have been searching for an explanation but everyone just didnt make any sense so thank you.
