electron, proton, neutrino

electron 

Pronunciation: /ɪˈlɛktrɒn/ 

NOUN

Physics

A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

Example sentences

The electron’s mass is about 9 × 10⁻²⁸g, 1,836 times less than that of the proton. Electrons orbit thepositively charged nuclei of atoms and are responsible for binding atoms together in molecules, as wellas for the electrical, thermal, optical, and magnetic properties of solids. Electric currents in metals and insemiconductors consist of a flow of electrons, and light, radio waves, X-rays, and much heat radiation are all produced by accelerating and decelerating electrons.

Origin

Late 19th century: from electric + -on.

proton 

Pronunciation: /ˈprəʊtɒn/ 

NOUN

Physics

A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron.

Example sentences

The mass of the proton is 1,836 times greater than that of the electron. The atoms of each chemical element have a characteristic number of protons in the nucleus; this is known as the atomic number. The common isotope of hydrogen has a nucleus consisting of a single proton.

Derivatives

protonic

Pronunciation: /prə(ʊ)ˈtɒnɪk/ 

ADJECTIVE

Example sentences

Origin

1920s: from Greek, neuter of prōtos 'first'.

neutrino 

Pronunciation: /njuːˈtriːnəʊ/ 

NOUN (plural neutrinos) 微中子

A neutral subatomic particle with a mass close to zero and half-integral spin, which rarely reacts with normal matter. Three kinds of neutrinos are known, associated with the electron, muon, and tau particle.

Example sentences

Origin

1930s: from Italian, diminutive of neutro 'neutral'.
