  3. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    Atomic numbers (Z) are a special case of charge numbers, referring to the charge number of an atomic nucleus, as opposed to the net charge of an atom or ion. The charge numbers for ions (and also subatomic particles ) are written in superscript, e.g., Na + is a sodium ion with charge number positive one (an electric charge of one elementary ...

  4. Mass-to-charge ratio - Wikipedia

    en.wikipedia.org/wiki/Mass-to-charge_ratio

    When charged particles move in electric and magnetic fields the following two laws apply: Lorentz force law: = (+),; Newton's second law of motion: = =; where F is the force applied to the ion, m is the mass of the particle, a is the acceleration, Q is the electric charge, E is the electric field, and v × B is the cross product of the ion's velocity and the magnetic flux density.

  5. Buckingham potential - Wikipedia

    en.wikipedia.org/wiki/Buckingham_potential

    Buckingham proposed this as a simplification of the Lennard-Jones potential, in a theoretical study of the equation of state for gaseous helium, neon and argon. [1] As explained in Buckingham's original paper and, e.g., in section 2.2.5 of Jensen's text, [2] the repulsion is due to the interpenetration of the closed electron shells.

  6. Ionic potential - Wikipedia

    en.wikipedia.org/wiki/Ionic_potential

    Ionic potential is the ratio of the electrical charge (z) to the radius (r) of an ion. [1]= = As such, this ratio is a measure of the charge density at the surface of the ion; usually the denser the charge, the stronger the bond formed by the ion with ions of opposite charge.

  7. Mass (mass spectrometry) - Wikipedia

    en.wikipedia.org/wiki/Mass_(mass_spectrometry)

    The dalton (symbol: Da) is the standard unit that is used for indicating mass on an atomic or molecular scale (atomic mass). [1] The unified atomic mass unit (symbol: u) is equivalent to the dalton. One dalton is approximately the mass of one a single proton or neutron. [2] The unified atomic mass unit has a value of 1.660 538 921 (73) × 10 ...

  9. Pearson–Anson effect - Wikipedia

    en.wikipedia.org/wiki/Pearson–Anson_effect

    Pearson-Anson oscillator circuit. The Pearson–Anson effect, discovered in 1922 by Stephen Oswald Pearson [1] and Horatio Saint George Anson, [2] [3] is the phenomenon of an oscillating electric voltage produced by a neon bulb connected across a capacitor, when a direct current is applied through a resistor.
