Question

define nuclear energy.​

Answer 1

Answer:

Nuclear energy, also called atomic energy, energy that is released in significant amounts in processes that affect atomic nuclei, the dense cores of atoms. ... It is distinct from the energy of other atomic phenomena such as ordinary chemical reactions, which involve only the orbital electrons of atoms.

Answer 2

Definition : The energy released during a nuclear reaction (fission or fusion process) is called nuclear energy.

Note : The energy released in these reactions are given by smaller unit of energy called electron volt (eV).

1 eV = 1.6 × 10^-19 J

Also, 1 MeV = 1.6 × 10^-13 J

and, 1 amu = 931 MeV

Hope, this would definitely help you out !
