5. Fission
Nuclear fission in the process whereby a nucleus, with
a high mass number, splits into 2 nuclei which have
roughly equal smaller mass numbers.

During nuclear fission, neutrons are released.
6. The Fission Process
A neutron travels at high speed towards a uranium-235
nucleus.

7. The Fission Process
The neutron strikes the nucleus which then captures the
neutron.

8. The Fission Process
The nucleus changes from being uranium-235 to
uranium-236 as it has captured a neutron.

9. The Fission Process
The uranium-236 nucleus formed is very unstable.
It transforms into an elongated shape for a short time.
10. The Fission Process
The uranium-236 nucleus formed is very unstable.
It transforms into an elongated shape for a short time.

14. Chain Reaction
Now three secondary neutrons are produced.Now each of these will
create three more and so on.Due to this chain reaction which happens
very quickky a lot of heat energy is produced.
26. Nuclear Fusion
In nuclear fusion, two nuclei combine to produce a single
nucleus with a higher mass number.
Fusion reactions do not occur naturally on our
planet but are the principal type of reaction
found in stars
The large masses, densities, and high
temperatures of stars provide the initial
energies needed to fuel fusion reactions
The sun fuses hydrogen atoms to produce
helium and vast amounts of energy.

27. Nuclear Holocaust
It is the large scale destruction and devastation
caused due to usage of nuclear weapons.
28. Nuclear Medicine
It is a branch or specialty of medicine and medical imaging
that uses radionuclides and relies on the process of
radioactive decay in the diagnosis and treatment of disease.
