Facts about
nuclear force
1. Nuclear force is a strong force
between nucleons that hold nucleus together
2. Nuclear force is what overcome the
strong coulomb force between proton of same charges
3. Without the nuclear force atomic
nucleus would not have existed.
4. The nature of nuclear force is yet
unknown
5. Nuclear force can be said to be
nucleon-nucleon interaction or residual strong force.
6. The nuclear force only exist within
the nuclear distance of about 1 femtometer.
7. Nuclear force depend on the spin of
protons and neutrons
8. The nuclear force is only felt
between a particles made up of quarks
9. The force is stronger for particle
with their spin aligned and weaker for particles with their spin anti-aligned.
10.
If
the spin of particles are anti-aligned the nuclear force is too weak to bind
them together e.g protons and protons or neutrons and neutrons.
11.
The
strong force is force between nucleons by exchange of particles called mesons.
12.
Two
or more nucleons must be very close enough for the meson exchange to be
sustained
13.
Nuclear
force is a very short range force.
14.
Nuclear
force is about 10 million times stronger than chemical bonding between
molecules.
15.
A nuclear specie in a nuclear reactor produces
energy million times greater that that produce by chemical compounds like
fossil fuels.
16.
A
femtometer is about 10-15 meters.
