Protons

 

The proton is the positively charged subatomic particle present in all atoms. The mass of the proton is about 1840 times the mass of the electron.

 

Discovery of the Proton

In 1886, Eugene Goldstein (1850-1930) discovered evidence for the existence of this positively charged particle. Utilizing a cathode beam tube with gaps in the cathode, he saw that there were beams going the other way from the cathode beams.

 

Summary

When an electron is removed from a hydrogen atom, a proton remains.

Goldstein observed rays travelling in the opposite direction of the cathode rays in a cathode ray tube.

He showed that these beams were sure particles and called the channel beams.
