Basic Electronics: Introduction for Beginners
It followed by identification of electron in 1897 and then invention of the vacuum tube. In this chapter you can study in detail: Electronics Definition Glossary of Electronic Terms Before you learn Basic Electronics, you must
Isotope | Examples & Definition | Britannica
A uniform scale of nuclear stability that applies to both stable and unstable isotopes alike is based on comparing measured isotope masses with the masses of their constituent electrons, protons, and neutrons.
Ion | Definition, Chemistry, Examples, & Facts
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field
Transition metal | Definition, Properties,
Transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one. They occupy the middle portions of
7.3: Electric Potential and Potential Difference
Figure 7.3.2 7.3. 2 shows a situation related to the definition of such an energy unit. An electron is accelerated between two charged metal plates, as it might be in an old-model television tube or oscilloscope. The electron gains
Subatomic particle
Subatomic particle - Electron, Muon, Tau: Probably the most-familiar subatomic particle is the electron, the component of atoms that makes interatomic bonding and chemical reactions—and hence life—possible. The electron was
Electric current | Formula & Definition | Britannica
Electric current, any movement of electric charge carriers such as electrons, protons, ions, or holes. Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point
Subatomic particle | Definition, Examples, & Classes | Britannica
Subatomic particle, any of various self-contained units of matter or energy that are the fundamental constituents of all matter. They include electrons, protons, neutrons, quarks,
Wave-particle duality | Quantum Mechanics,
Wave-particle duality, possession by physical entities (such as light and electrons) of both wavelike and particle-like characteristics. On the basis of experimental evidence, German physicist Albert Einstein first showed (1905)
Electron shell | Definition & Facts
Electron shell, regions surrounding the atomic nucleus containing a specific number of electrons. Each allowed electron orbit is assigned a quantum number n that runs from 1 (for the orbit closest to the nucleus) to infinity (for
Cathode and Anode
Cathode and Anode are commonly used terms in the context of electrochemistry, specifically in electrochemical cells like batteries and electrolytic cells. An anode is a negative or reducing electrode that releases electrons and
Electron Affinity
Electron Affinity is a measure of the attraction between an incoming electron and the nucleus of an atom or molecule. It is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron
Plasma | Physics, State of Matter, & Facts
Plasma, in physics, an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized. It is sometimes referred to
Basic Electronics: Introduction for Beginners
Electronics is the study of electrical circuits consisting of active electrical components such as transistors, diodes, integrated circuits (IC), vacuum tubes, silicon-controlled rectifiers (SCRs). These components manipulate the
¿Qué es un electrón?
En este artículo descubrirás qué son los electrones, cuáles son sus características y propiedades, cómo se originan y qué aplicaciones tienen en la ciencia y la tecnología moderna.
Ionizing radiation | Definition, Sources, Types,
Ionizing radiation, flow of energy in the form of atomic and subatomic particles or electromagnetic waves that is capable of freeing electrons from an atom, causing the atom to become charged (or ionized). Ionizing radiation
Bohr model | Description, Hydrogen,
Bohr model, description of the structure of atoms proposed in 1913 by the Danish physicist Niels Bohr. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated
