What is the Value of Electrons?
An electron is a subatomic particle commonly represented as e– or e. It possesses negative polarity. An electron inherits the properties like – Charge, Mass, Spin, etc. The values of electrons imply the value of the charge of an electron, the mass of the electron, and a quantum mechanical property- spin of the 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 coulombs
The charge of an electron is responsible for the electric charge.
Mass of Electron
The mass of an electron 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 electrons 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 an electron is half-integral values:
s = ½
