33 interesting facts about protons

Facts about protons

1.      a proton is positively charged

2.     The charge on proton is same magnitude as that on electron but opposite.

3.     The number of protons and electron are equal in a neutral atom.

4.     A proton is made of two up quarks and one down quark.

5.     The sum of charges in the three quarks add up to one.

6.     The proton diameter is not greater than 10^-15 therefore it is a fermion.

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

8.     Proton is represented by a symbol p or p⁺.

9.     The antiparticle of proton is called antiproton, same as proton but with opposite charges.

10.                        The proton was discovered by sir Earnest Rutherford.

11.                        It has a mass of 1.672x10^-27kg 

12.                        Proton is stable with mean lifetime of 2.1x10²⁹ years.

13.                        The magnitude of charge on proton is 1.602x10^-19c.

14.                        The number of protons determine the atomic number, nuclear charge and chemical properties of atoms.

15.                        Two protons is lost by an atom when it undergo alpha decay.

16.                        Proton and electron is produced when a neutron split in beta decay.

17.                        The proton and neutrons constitute the atomic  nucleus.

18.                        The proton is slightly lighter than proton by 0.2% and 1840 times heavier than an electron.

19.                        The only atomic nucleus with neutron alone is the hydrogen.

20.                        It is a hadron because it has quarks.

21.                        It is a baryon.

22.                        Quarks are the fundamental building blocks of all matters.

23.                        The rest mass of the three quarks constitute only 1% of the mass of the proton.

24.                        The rest of the quarks + the energy of the gluons + kinetic energy of the quarks is what constitute the proton mass.

25.                        The radius of the proton is between 0.8 to 0.857 fm.

26.                        Quarks in proton are held by the strong nuclear force intermediated by gluons.

27.                        Can we say proton is fundamentally stable? Because of its large mean lifetime.

28.                        Free protons are found in plasma because high temperature does not allow them to combine with electrons.

29.                        Protons are produced from the radioactive decay of neutrons.

30.                        Protons transform to neutron through electron capture or inverse beta decay.

31.                        The mass of proton is the constituent mass of its quarks and not the current mass.

32.                        The current mass is the sum of the rest masses the three quarks.

33.                        Chemical behavior of atoms does not affect the protons.
