Following the reviews of atomic-weight determinations and other cognate data in 2015, 2017, 2019 and 2021, the IUPAC (International Union of Pure and Applied Chemistry) Commission on Isotopic Abundances and Atomic Weights (CIAAW) reports changes of standard atomic weights. The symbol Ar°(E) was...
Theatomic numberof plutonium is 94, meaning allatomsof plutonium have 94 protons. It has an atomic weight around 244, a melting point of 640 degrees C (1183 degrees F), and a boiling point of 3228 degrees C (5842 degrees F). Plutonium oxide forms on the surface of plutonium exposed to...

I am an afficionado of all weaponry, and there is this question I have which has bugged me for a while. What, exactly, makes a Hydrogen bomb different from an atomic bomb? I realize that the explosive is Hydrogen as opposed to Uranium or Plutonium, but why is it more powerful?
