What is an Electron?
A negative electrical charge with a stable subatomic particle is called an electron. They are not constructed from even smaller components like neutrons and protons. Every electron has one unit of negative charge and a very small mass in comparison to neutrons and protons. It has an electronic charge of -1. They are the smallest particles that make an atom. For example, the hydrogen atom has only one electron and one proton. In an atom, the number of electrons is equal to the atomic number of an element.
