Electron

An electron is a subatomic particle with a negative charge. It is one of the fundamental particles that make up an atom. Electrons are found in a cloud-like region surrounding the nucleus of an atom.

Properties of Electrons

• Charge: Electrons have a negative charge, which is equal in magnitude to the positive charge of a proton.
• Mass: The mass of an electron is about 1/1836th the mass of a proton.
• Spin: Electrons have a property called spin, which is a fundamental property related to their angular momentum.
• Wave-Particle Duality: Electrons exhibit both wave-like and particle-like behavior, as described by quantum mechanics.

Role of Electrons in Atoms

Electrons play a crucial role in determining the chemical and physical properties of an element. They are involved in chemical bonding, and their arrangement in the electron cloud determines an element's reactivity and behavior in chemical reactions.
