electron Definition

elec·tron (ē lek′trän′, i-; also, --trən)

noun

Particle Physics the lightest elementary particle with an electric charge: it is a lepton with a negative charge of c. 1.602 × 10 coulomb and a rest mass of c. 9.109 × 10 kg (c. 0.511 MeV/c), which is c. of the mass of a proton: ordinarily an atom has the same number of negative electrons around the nucleus as the number of positive protons in the nucleus

Etymology: coined (1891) by G. J. Stoney (1826-1911), Ir physicist < electr(ic) + -on

  • delocalise: The hydrogen atoms aren't involved in any way with the delocalised electrons.
  • eject: Ultimately the electrons ejected from the surface in the de-excitation process will be imaged to develop the technique into a microscopy.

Adjective modifier

  • unpaired: A free radical is an atom or compound which contains an unpaired electron.
  • relativistic: It is associated with relativistic electrons or cosmic ray electrons, so named because they travel at speeds comparable with that of light.
  • outer: Elements from group 3 across to the noble gases all have their outer electrons in p orbitals.
