Question

The energy stored in an atomic nuclei of elements is known as _________.

• A. nuclear fusion
• B. nuclear fission
• C. nuclear energy
• D. nuclear cell

Answer 1

The correct option is C nuclear energy

The energy stored in atomic nuclei, or in the core, of the elements is known as nuclear energy. The nucleus of an atom contains protons and neutrons, the attractive force between neutrons and protons is called as nuclear force, which tends to bind them. These forces balance each other, thereby making the nucleus of an atom stable.When, under certain conditions, splitting of a heavier nucleus into smaller fragments or union of smaller nuclei forming a heavier nucleus occurs, a fraction of the mass is converted into energy which is called as nuclear energy.
