Electron

An electron is a fundamental subatomic particle with a negative electric charge. It orbits the nucleus of an atom, forming a cloud of probability within specific energy levels. These particles are incredibly light, about 1/1836 the mass of a proton, and are a key component of electricity, contributing to the flow of electric current in conductors. electron behavior dictates chemical bonding and the properties of materials. Their interactions with other particles, such as photons, underpin various physical phenomena, including light emission and absorption.

Electron meaning with examples

• In a copper wire, electrons move through the metal, generating an electric current that powers our homes and devices.
• The cathode ray tube in older televisions used a beam of electrons to excite phosphors on the screen, creating an image.
• During photosynthesis, plants use light energy to energize electrons, which drive the production of glucose.
• The collision of electrons in a particle accelerator helps scientists study the fundamental forces of nature.
• Semiconductor devices, like transistors, rely on controlling the flow of electrons to create electronic circuits.
