A nuclear reaction between an uranium isotope (e.g. uranium 238) and deuterons.
Uranium
Being a metal Uranium would conduct electricity.
Uranium minus a proton (hydrogen atom) is protactinium.? That is, if you could get it to do that - this is an unusual reaction.
Uranium 235 has 143 neutrons; absorbing a neutron (neutron,gamma reaction) the isotope uranium-236 is obtained.
For example, metallic uranium is soluble in nitric acid.
1. Yes, all coals contain traces of uranium. 2. Uranium is not combustible; the "burning" of uranium in nuclear reactors is a nuclear reaction, not a reaction with oxygen.
A nuclear fission reaction.
The nuclear fission of uranium is a reaction with neutrons.
A nuclear reaction between an uranium isotope (e.g. uranium 238) and deuterons.
Any reaction.
Uranium
Being a metal Uranium would conduct electricity.
The element is determined by the number of protons. When uranium captures a fast neutron it is still uranium but has an increased atomic mass. Fast neutron capture may encourage a further reaction but it depends on which uranium isotope you start with as to the increase in probability some further reaction will occur and which reaction that might be.
Nuclear fission
It is possible but this reaction was not studied.
Uranium metal (enriched in uranium-235 up to 99 %) is a nuclear explosive, if the critical mass is reached. Also criticality accidents are possible in uranium plants or uranium storage areas.
