Is hydrogen more explosive than helium?

Answer 1

No. The single largest release of energy from combining 2 of the same nuclei is for hydrogen nuclei.

However it is unlikely that 2 helium nuclei would fuse directly anyway, as the double positive charges on each would strongly repel each other. It is more likely the heavier elements would be formed as single protons, neutrons and deutirium nuclei fused with helium nuclei.

Helium fusion of 2 helium atoms is a "prohibited" process, its product is a radioactive isotope of beryllium that decays back to helium before it could get a chance to fuse with anything. To fuse helium you must get up to a very high density, pressure, and temperature where the very rare fusion reaction of 3 helium atoms simultaneously into carbon occurs. This reaction is what fuels the white hot core of red giants and heats their inner layers enough to expand their photosphere into gigantic size where it cools to red heat.

All following elements are produced from stages of fusion of pairs of nuclei until iron is produced, which cannot be fused. Elements between direct fusion products are produced mostly from neutron captures and radioactive decay.

Elements past nickel and iron can only be produced in supernova explosions.

Answer 2

It's the other way around. Hydrogen is fused into helium in proton-proton fusion.

Answer 3

Yes that is why we can not take to much in as it can make an explosion in our bodies x

Answer 4

Yes, hydrogen is more explosive.

Answer 5

Yes

Answer 6

yes
