The phrase "a number of electron" is not correct in written English.
The correct form should be "a number of electrons" as "electron" needs to be pluralized when referring to multiple particles.
Example: "In the experiment, a number of electrons were emitted from the cathode."
Alternatives: "several electrons" or "multiple electrons".
We demonstrate the usefulness of Medipix1-like detectors for a number of electron diffraction patterns from inorganic and biological specimen.
Complex reaction mechanisms can consist of a number of electron transfer steps, with some chemical steps preceding or succeeding the electron transfer steps or taking place in between them.
This longitudinal feedback system has been commissioned and optimized to stabilize high-current electron beams with a wide range of electron beam energies (250 MeV to 1.15 GeV) and a number of electron beam bunch modes, including the single-bunch mode and all possible symmetric bunch modes.
In this work, such methodology based on nanoindentation mapping supported by a number of electron microscopy visualization techniques will be examined at the example of Ga-modified As2Se3 glasses.
A number of electron density peaks in the solvent region were attributed to sulfate ions.
A number of electron microphotographs are presented showing the various aspects of phagocytosis of fibers in lung tissue.
A number of electron-donating (ED) and electron-withdrawing (EW) units based on Dewar's rules are substituted into the π-conjugated oligo-phenylenevinylene bridge of the reference TA-St-CA dye.
An X-ray photon absorbed by the material excites a number of electrons from its valence band to the conduction band.
So you'll notice in your problem-set, sometimes you're asked for a number of orbitals with a set of quantum numbers, sometimes you're asked for a number of electrons for a set of quantum numbers.
Each group consists of elements that have similar electronic structures characterized by completely filled inner electron shells and by a number of electrons in their outermost shells equal to the group number.
Since materials are complex many-body systems composed of a number of electrons and nuclei, it has been difficult to compute atomic structures and physical and chemical properties without experimental help.
