An electron is a subatomic particle. Commonly represented as e– or e. It posses negative polarity. An electron inherits the properties like – Charge, Mass, Spin etc. The values of electron imply the value of charge of electron, mass of electron and a quantum mechanical property- spin of electron along with corresponding units.
Charge Of Electron
The electric charge by an Electron is the unit elementary negative charge. The value is –
e– = 1.60217662 × 10-19 Coulomb’s
The charge of electron is responsible for the electric charge.
Mass Of Electron
The mass of election is 1/1836 of proton mass. The value of electron mass is-
me = 9.10938356 × 10-31 Kilograms.
The values of charge and mass of electron are commonly used in solving problems in physics.
Electron Spin
Spin or angular momentum is an intrinsic quantum mechanical property of subatomic particles. The spin of electron is half-integral values
S = ½
