36 Facts About Neutrons

Facts about the neutron,

1.     The neutron is found  in the nucleus of an atom

2.     It s electrically neutral

3.     Neutron has one up quark and two down quarks

4.     Quarks are the fundamental building blocks of matters

5.     A neutron is a fermions

6.     It is affected by strong and weak nuclear interactions, gravity and electromagnetic interactions.

7.     The antiparticle of neutron is antineutrino

8.     Discovered by James Chadwick

9.     The mass of neutron is 1.67x10^-27kg. In kilograms

10.                        The mass of neutron in electron volt is 939.56mev

11.                        It is slightly heavier  than proton

12.                        Neutron are responsible for isotopes

13.                        Atoms with same atomic number but different mass are called isotopes.

14.                        Protons are responsible for variation in nuclear mass of same atom.

15.                        Both proton and neutron are separately called nucleon.

16.                        The sum of proton and neutron gives the atomic mass.

17.                        Nuclides and isotopes mean same thing.

18.                        Neutrons are responsible for self-sustaining nuclear chain reaction.

19.                        Neutrons are radioactive and decay when outside a nucleus.

20.                        Major source of neutron are neutron generators, research reactors etc

21.                        Hydrogen only isotope without neutron.

22.                        A free neutron has a half life of 15minutes.

23.                        A free neutron is radioactive and disintegrates into proton, electron and antineutrino.

24.                        Free neutron decays through beta decay.

25.                        Free proton is stable while free neutron is unstable.

26.                        In nuclear reaction absorption of neutron make atoms unstable and nuclear fission follows.

27.                        Neutron is a hadron because it made up of quarks

28.                        Neutron is a baryon because it has three quarks.

29.                        In neutron the sum of electric charge on two down quarks and one up quarks add up to zero.

30.                        The quarks in neutron are held by strong interactions.

31.                        The force in neutron is mediated by gluons.

32.                        Gluons are quantum of interaction or mediating particles in strong nuclear interactions.

33.                        Neutron was discovered in 1932.

34.                        The neutron is a projectile or bombarding particles in nuclear fission reaction.

35.                        When neutron interacts with unpaired electron it results to magnetic scattering.

36.                        The neutron has a spin of ½.
