Interesting Facts About Protons



Protons are small subatomic particles found in the nucleus of atoms.

They have a positive charge.                                                                                                                                           

The number of protons in an atom of an element is the atomic number.

The atomic number is used to identify an atom.                                                                                                                  

In the box below, the atomic number shows the number of protons.

Atomic Mass 



Adding or removing protons from the nucleus of an atom creates a different element.

For example, removing one proton from an atom of oxygen creates a nitrogen atom. Add a proton to hydrogen and you make helium!



Interesting Facts about Protons:


The mass of the proton is about 1,840 times the mass of the electron and slightly less than the mass of the neutron.
