Atomic energy includes the sum of the energy included in an atom. Nuclear energy includes the energy released when changes are done to the nucleus of an atom. This the main difference between atomic energy and nuclear energy.
Why atomic energy is called nuclear energy?
Nuclear energy is the energy in the nucleus, or core, of an atom. … As they split, the atoms release tiny particles called fission products. Fission products cause other uranium atoms to split, starting a chain reaction. The energy released from this chain reaction creates heat.
What is atomic energy also called?
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.
What is the difference between nuclear energy and nuclear fusion?
Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. … Nuclear fission releases heat energy by splitting atoms.
What is atomic energy used for?
Atomic energy is the source of nuclear power, which uses sustained nuclear fission to generate heat and electricity. It is also the source of the explosive force of an atomic bomb.

What is the example of atomic energy?
The energy that is released through a nuclear reaction or radioactive decay process. Of particular interest is the process known as fission, which occurs in a nuclear reactor and produces energy usually in the form of heat.
Where is nuclear energy used?
Top five nuclear electricity generation countries, 2019
|Country||Nuclear electricity generation capacity (million kilowatts)||Nuclear share of country’s total electricity generation|
What are 3 sources of nuclear energy?
Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.
Why is nuclear fusion not used?
Normally, fusion is not possible because the strongly repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to collide and for fusion to occur. … The nuclei can then fuse, causing a release of energy.
Why is nuclear fusion so hard?
In the sun, the extreme pressure produced by its immense gravity create the conditions for fusion to happen. The amount of energy produced from fusion is very large — four times as much as nuclear fission reactions — and fusion reactions can be the basis of future fusion power reactors.
How efficient is nuclear fusion?
One kilogram of fusion fuel could provide the same amount of energy as 10 million kilograms of fossil fuel. A 1 Gigawatt fusion power station will need less than one tonne of fuel during a year’s operation.
