ELECTRON MICROGRAPH, noun. A micrograph produced using an electron microscope.
ELECTRON MICROGRAPHS, noun. Plural of electron micrograph
ELECTRON MICROSCOPE, noun. Any of several forms of microscope that use a beam of electrons, rather than one of light, and thus has a much greater resolving power.
ELECTRON MICROSCOPES, noun. Plural of electron microscope
ELECTRON MICROSCOPY, noun. Microscopy carried out using an electron microscope
ELECTRON NEUTRINO, noun. A leptonic elementary particle, having near-zero mass and no charge
ELECTRON NEUTRINOS, noun. Plural of electron neutrino
ELECTRON NUMBER, noun. (physics) The number of electrons in an atom or ion

ELECTRON SHELL, noun. (physics) The collective states of all electrons in an atom having the same principal quantum number (visualized as an orbit in which the electrons move).
ELECTRON SPIN RESONANCE, noun. (physics) The absorption of radiation by species having unpaired electrons when placed in a magnetic field that is used spectroscopically to detect and study free radicals
ELECTRON TRANSFER REACTION, noun. (chemistry) a reaction in which a single electron is transferred from one molecule to another; one being oxidized and the other reduced (also known as a redox reaction); long-range electron transfer reactions are important in biological reactions involving metalloproteins such as haemoglobin
ELECTRON TRANSFER REACTIONS, noun. Plural of electron transfer reaction
ELECTRON TUBE, noun. (physics) Any of several devices consisting of a sealed chamber, either evacuated or filled with gas at low pressure, in which an electric current flows between electrodes.
