Question

Compare an electron and a proton in respect of mass and charge

Answer 1

An electron has a mass of zero (0) while a proton has a mass of 1 (a.m.u.)
An electron has a negative charge (-1) while a proton has a positive charge (+1)

NB
The mass of an electron is so negligible that it is considered to have a mass of zero. The mass of an electron is about 1/1840 that of a proton.
Thank you.

Answer 2

The mass of electon is very small i.e. 9.1 X 10 power-31kg whereas proton has mass 1.602 X 10 power-27kg .
