This document outlines the key differences between nuclear fusion and fission. It defines fusion as the process where two light atoms combine to form a heavier atom, releasing energy. This occurs in stars like our Sun and involves hydrogen fusing to form helium. Fission is defined as the splitting of heavy atoms like uranium, where the atom absorbs a neutron and splits into smaller atoms, releasing energy. Examples of both fusion and fission reactions are provided.

3. What is the Fusion:
Fusion occurs when two light atoms bond together, or fuse, to make a
heavier one . The total mass of the new atom is less than that of the
two that formed it; the "missing" mass is given off as energy, as
described by Albert Einstein's famous E=mc2 equation.
4. What is the fusion of atom:
Fusion occurs when two atoms slam together to form a heavier atom , like
when two hydrogen atoms fuse to form one helium atom. This is the same
process that powers the sun and creates huge amounts of energy—several
times greater than fission. It also doesn't produce highly radioactive vision
products.
5. Example of the Fusion:
Like fission, nuclear fusion can also transmute one element into another. For
example, hydrogen nuclei fuse in stars to form the element helium. Fusion is
also used to force together atomic nuclei to form the newest elements on
the periodic table.
6. What is fusion of sun:
In the core of the Sun hydrogen is being converted into helium. This is
called nuclear fusion. It takes four hydrogen atoms to fuse into each
helium atom. During the process some of the mass is converted into
energy.
7. What is The Fusion nuclear :
Nuclear fusion is a reaction in which two or more atomic nuclei are
combined to form one or more different atomic nuclei and subatomic
particles (neutrons or protons). The difference in mass between the
reactants and products is manifested as either the release or the absorption
of energy.
8. Converting Hydrogen to Helium:
Fusion joins atomic nuclei together. The element formed has more
neutrons or more protons than that of the starting material. For
example, hydrogen can fuse to form helium.
9. What is the fission:
Fission occurs when a neutron slams into a larger atom, forcing it
to excite and split into two smaller atoms also known as fission
products. Additional neutrons are also released that can initiate a
chain reaction. When each atom splits a tremendous amount of
energy is released.
10. What is nuclear fission:
In nuclear fission, atoms are split apart, which releases energy. All nuclear
power plants use nuclear fission, and most nuclear power plants use uranium
atoms. During nuclear fission, a neutron collides with a uranium atom and
splits it, releasing a large amount of energy in the form of heat and radiation.
11. Example of fission:
A common fission reaction produces barium-141 and krypton-92. In this
particular reaction, one uranium nucleus breaks into a barium nucleus, a
krypton nucleus, and two neutrons. These two neutrons can go on to split
other uranium nuclei, resulting in a nuclear chain reaction.
12. Fission and fusion:
In fission, energy is gained by splitting apart heavy atoms, for example
uranium, into smaller atoms such as iodine, cesium, strontium, xenon
and barium, to name just a few. However, fusion is combining light
atoms, for example two hydrogen isotopes, deuterium and tritium, to
form the heavier helium.
