Core Definition of Atomic Energy Definition
Atomic energy, also known as nuclear energy, is the energy released from the nucleus of an atom during nuclear reactions. This energy can be produced through two main processes: nuclear fission, where the nucleus of an atom is split into smaller parts, and nuclear fusion, where two light nuclei combine to form a heavier nucleus. Atomic energy is a powerful source of energy used in various applications, from electricity generation to medical treatments.
Understanding Atomic Energy by Grade Level
Elementary School Definition (K-5 Grade)
Atomic energy is the energy that comes from the tiny particles inside atoms. It can be used to make electricity and help in other important ways, like in hospitals.
Middle School Definition (Grade 6-8)
Atomic energy is the energy stored in the nucleus of an atom. It can be released during nuclear reactions, such as fission, where atoms are split, or fusion, where atoms are combined. This energy is used to generate electricity and in other technologies.
High School Definition (Grade 9-12)
Atomic energy, also referred to as nuclear energy, is the energy held in the bonds within an atom’s nucleus. It is released during nuclear reactions like fission, where heavy atoms are split, or fusion, where light atoms combine. This energy is harnessed in nuclear power plants, providing a significant source of electricity, and is also utilized in medical and scientific fields.

Atomic Energy Definition
- Atomic energy is energy generated by carrying out controlled chemical reactions.
- Atomic energy is one of the most sought after types of energy these days, as it is considered a substitute to the conventional sources of energy.
- In simple ways, you can note that certain reactions like fusion and fission help in forming this atomic energy.
- Atomic energy is formed in a nuclear reactor, which is used to control chemical reactions.
- Some of the important definitions related to atomic energy are defined here:
Nuclear Fission
- Nuclear fission is a process in which the nucleus of an atom splits into two or more smaller nuclei as fission products, and usually some by-product particles.
- The by-products of nuclear fission include free neutrons, photons usually in the form gamma rays, and other nuclear fragments such as beta particles and alpha particles.
Isotope
Isotopes are forms of an element whose nuclei have the same atomic number–-the number of protons in the nucleus–but different mass numbers
Proton
The proton is a subatomic particle with an electric charge of one positive fundamental unit and a mass of 938.3 MeV/c2, or about 1836 times the mass
Radioactive decay
Radioactive decay is the set of various processes by which unstable atomic nuclei (nuclides) emit subatomic particles (radiation).
Potential energy
Potential energy is stored energy. Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects
Subatomic particle
A subatomic particle is a particle smaller than an atom: it may be elementary or composite.
Quantum number
A quantum number describes the energies of electrons in atoms. Each quantum number specifies the value of a conserved quantity
Hydrogen-like atom
Hydrogen-like atoms (or hydrogenic atoms) are atoms with one single electron.
Important events in history of atomic energy
- In 1780 German scientist Martin Heinrich Klaproth discovers Uranium. That becomes the keystone of atomic energy.
- In march 1986 French scientist Antoine Becquerel discovers radioactivity.
- In 1934 Italian scientist Enrico Fermi shows that neutrons can split atoms.
- In July 1939 Enrico Fermi and Leo Sziland propose a idea of nuclear reactor that uses Uranium fuel.
- In December 1951, First electric energy from a nuclear power plant was produced in Arco,Idaho. It powers four electric bulbs.
- Finally world’s first commercial nuclear power plant opens in obninsk soviet union. It has 6 megawatt capacity.

FAQ on Atomic Energy Definition
What is the basic definition of atomic energy?
Atomic energy, also known as nuclear energy, is the energy released by the nucleus of an atom during nuclear reactions, such as fission or fusion.
How is atomic energy produced?
Atomic energy is produced through nuclear reactions, where the nucleus of an atom is split (fission) or combined with another nucleus (fusion), releasing a large amount of energy.
What are some uses of atomic energy?
Atomic energy is used in electricity generation through nuclear power plants, in medical treatments such as cancer radiotherapy, and in scientific research.
