The word proton is Greek for "first", and this name was given to the hydrogen nucleus by Ernest Rutherford in 1920. In previous years, Rutherford had discovered that the hydrogen nucleus (known to be the lightest nucleus) could be extracted from the nuclei of nitrogen by atomic collisions.

Discovered:

Observed as H+ by Eugen Goldstein(1886). Identified in other nuclei (and named) byErnest Rutherford (1917–1920)

Charge radius:

0.8751(61) fm

Electric charge:

+1 e; 1.6021766208(98)×10−19 C
