Protons and neutrons are subatomic particles located in the atomic nucleus.
These particles are the electrons.

Protons and Neutrons
Subatomic particles are: neutron, proton, electron.
J.J. Thomson discovered the electron in 1897.
3 protons and 4 neutrons
Atoms can have anywhere from 1 to somewhere around 260-290 subatomic particles. The protons and neutrons are located in a clump in the center of the atom, surrounded by rapidly revolving electrons
