In atoms, an electron's matter wave occupies atomic orbitals around a positively charged atomic nucleus. The configuration and energy levels of an atom's electrons determine the atom's chemical …

Nov 20, 2025 · electron, one of the three basic subatomic particles —along with protons and neutrons —that make up atoms, the basic building blocks of all matter and chemistry. The negatively charged …

Dec 8, 2018 · Learn what an electron is. Get its definition, learn where to find electrons, and understand the properties of this type of matter.

The electron is a subatomic particle that is found in all atoms. Unlike protons, neutrons, or the nuclei of atoms, electrons are elementary particles. This means they are not made of even smaller particles. …

May 21, 2024 · Electrons are elementary subatomic particles with negligible mass that surround the nucleus of an atom. They are bound to the nucleus due to electromagnetic attraction, with neutral …

Jun 9, 2025 · Electrons are negatively charged particles found outside the nucleus of an atom. Electrons are much lighter than protons and are key in conducting electricity in solids.

Jul 23, 2025 · Electrons are subatomic particles that have an elementary charge of (-1) magnitude. The charge held by an electron is equal in magnitude and has the opposite sign to the charge carried by …

Jun 1, 2025 · Electrons became the building blocks of charge, interaction, and motion—key players in a universe that was far more dynamic and mysterious than Newton had imagined.

ELECTRON definition: an elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 × 10 −19 coulombs, a mass of 9.108 × 10 −31 kilograms, and spin of ½, …
