Webelectron: An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom . Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron. WebThe ampere (/ ˈ æ m p ɛər /, US: / ˈ æ m p ɪər /; symbol: A), often shortened to amp, is the unit of electric current in the International System of Units (SI). One ampere is equal to 1 …
