Electron
what is electron?
An electron is a subatomic particle that carries a negative electric charge. It is one of the fundamental constituents of matter and is a key building block of atoms. Electrons orbit the atomic nucleus in specific energy levels, and their arrangement determines the chemical properties of an element.
The concept of the electron is a fundamental part of the atomic model. In a neutral atom, the number of electrons is equal to the number of protons in the nucleus, which carries a positive charge. Electrons have a much smaller mass compared to protons and neutrons, making them lightweight particles.
Electrons play a crucial role in various physical phenomena, including electricity and magnetism. They are involved in chemical reactions, bonding between atoms, and the behavior of materials. Understanding the behavior of electrons is essential in fields such as physics, chemistry, and electronics.
