Enter a nuclear equation for the fusion of two h-2 atoms to form he-3 and one neutron. express your answer as a nuclear equation
aliya0001 [1]

The nuclear equation that represents the fusion of two H-2 atoms to form He-3 and one neutron is

\frac{2}{1} h + \frac{2}{1} h >  >  >  >  \frac{3}{2} he   +  \frac{1}{0} n

In a nuclear reaction the nuclides are represented with the chemical symbol preceded by a superscript that represents the mass number (number of protons plus neutrons) and a subscript that represents the atomic number (number of protons).

<h3>What is a Nuclear reaction ?</h3>

A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.
