What is an Electron

An electron is a subatomic particle that has a negative charge and is found in the outermost shell of an atom. Electrons are incredibly small, with a mass that is almost 1,000 times smaller than that of a proton. They are also extremely fast, moving at nearly the speed of light.

Electrons are a fundamental part of atoms, and are responsible for many of their properties. For example, the number of electrons in an atom determines its atomic number and, therefore, its identity as a specific element. Electrons are also involved in chemical reactions, as they can transfer from one atom to another to form chemical bonds.

In addition to their role in atoms, electrons are also a crucial part of many electrical and electronic devices. When an electrical current is applied to a material, electrons can move freely through it, allowing electricity to flow. This movement of electrons is what powers many of the devices we use every day, including computers, phones, and lights.

Overall, electrons are a fundamental building block of the universe, and their properties and behavior play a crucial role in many aspects of our daily lives.
