Electron
An electron is a subatomic particle that carries a negative electric charge. It is a fundamental component of matter and is found orbiting the atomic nucleus in specific energy levels.
Properties of Electrons
- Charge: The charge of an electron is -1.602 x 10-19 coulombs.
- Mass: The mass of an electron is approximately 9.109 x 10-31 kilograms.
- Location: Electrons are located outside the atomic nucleus in specific energy levels or orbitals.
- Spin: Electrons possess a property called spin, which is a quantum mechanical property that contributes to the magnetic moment of an atom.
Role of Electrons
Electrons play a crucial role in determining the chemical and physical properties of elements. They are involved in chemical bonding, the formation of ions, and the generation of electricity.
