Inside stars in space, the nuclei of hydrogen atoms fuse together to form helium atoms. this represents which form of energy? electrical energy nuclear energy chemical energy radiant energy

nuclear energy

Explanation:

Nuclear energy is the form of energy which is contained in the nuclei of the atoms.

In the nuclear fusion of the hydrogen, two (or more) hydrogen atoms fuse together into a helium nucleus. The final mass of the helium nucleus is lower than the sum of the masses of the original nuclei of hydrogen: this means that part of the mass has been converted into energy, according to Einstein's equation

where

is the variation of mass between final products and initial nuclei

c is the speed of light

The final energy is in the form of radiation/kinetic energy of the products, while the initial form of energy, which is contained in the nuclei of the atoms, is called nuclear energy.
