![]() In actuality, this analogy is inadequate. Spin is sometimes likened to the classical property of angular momentum, as in classical physics, a charged body rotating on its own axis will produce a magnetic field. The spin of an electron determines the strength of the magnetic moment it produces, and how the electron is deflected in an electromagnetic field. Every electron has an intrinsic spin of 1/2. In addition to charge, each electron has a property called spin. ![]() This charge is exactly equal and opposite to the charge of a single proton. The charge possessed by the electron is the smallest possible negative unit of electric charge, so its value is often called the elementary unit of charge. Each electron has an electric charge of about −1.602×10 −19 coulombs. Properties Of ElectronsĮlectrons are considered elementary particles, meaning that they do not have any proper parts or substructures. ![]() Additionally, electrons (along with positively charged particles like protons) are responsible for the phenomena of electromagnetism. depends on intermolecular electrostatic interactions. Chemical bonding is determined by electron activity, molecular shape is determined by electrostatic potential, color is determined by the absorption of light by electrons, and the phase behavior of substances (freezing, melting, sublimation, etc. As such, the electron is the least massive of the normal subatomic particles by far.Įlectrons are directly responsible for the bulk of a substance’s physical and chemical behavior. 1 This quantity is about equal to 1/1836th the mass of a proton. Electrons are considered elementary particles because they do not appear to have any smaller parts or substructures. The electron is one of the most important particles in the Standard Model of particle physics and is one of the 3 primary constituents (along with the proton and neutron) of ordinary baryonic matter. An electron is a subatomic particle that has a fundamental unit of negative charge e −.
