Electron has a mass 1/1836th times the mass of proton m=9.1×10⁻²⁷kg where mp=1.67×10⁻²¹kg
What is the mass of electron?
Electron and proton are the subatomic particles of negligible mass. However, the mass of an electron was discovered to be 1/1836th times
the mass of proton with help of mass spectroscopy
Due to this very reason, the atomic mass of a cation does not change after donating an electron
Hence, the mass of electron me=9.1×10⁻²⁷ kg 1/1836th times less than the mass pf proton mp=1.67×10⁻²¹kg
