  2. Electronvolt - Wikipedia

    en.wikipedia.org/wiki/Electronvolt

    It is common in particle physics, where units of mass and energy are often interchanged, to express mass in units of eV/c 2, where c is the speed of light in vacuum (from E = mc 2). It is common to informally express mass in terms of eV as a unit of mass, effectively using a system of natural units with c set to 1. [3] The kilogram equivalent ...

  3. Quantities, Units and Symbols in Physical Chemistry

    en.wikipedia.org/wiki/Quantities,_Units_and...

    Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...

  4. Atomic units - Wikipedia

    en.wikipedia.org/wiki/Atomic_units

    A set of base units in the atomic system as in one proposal are the electron rest mass, the magnitude of the electronic charge, the Planck constant, and the permittivity. [6] [9] In the atomic units system, each of these takes the value 1; the corresponding values in the International System of Units [10]: 132 are given in the table.

  5. Ionization energies of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Ionization_energies_of_the...

    The first of these quantities is used in atomic physics, the second in chemistry, but both refer to the same basic property of the element. To convert from "value of ionization energy" to the corresponding "value of molar ionization energy", the conversion is: 1 eV = 96.48534 kJ/mol 1 kJ/mol = 0.0103642688 eV [12]

  6. Units of energy - Wikipedia

    en.wikipedia.org/wiki/Units_of_energy

    In physics and chemistry, it is common to measure energy on the atomic scale in the non-SI, but convenient, units electronvolts (eV). 1 eV is equivalent to the kinetic energy acquired by an electron in passing through a potential difference of 1 volt in a vacuum. It is common to use the SI magnitude prefixes (e.g. milli-, mega- etc) with ...

  7. Ionization energy - Wikipedia

    en.wikipedia.org/wiki/Ionization_energy

    Ionization energy trends plotted against the atomic number, in units eV.The ionization energy gradually increases from the alkali metals to the noble gases.The maximum ionization energy also decreases from the first to the last row in a given column, due to the increasing distance of the valence electron shell from the nucleus.

    We explain EPA ratings, factors affecting range, how EVs performed in our testing, and why it's all complicated and different from the gas-powered-vehicle norm. EV Range: Everything You Need to ...

  9. Binding energy - Wikipedia

    en.wikipedia.org/wiki/Binding_energy

    Among the chemical elements, the range of ionization energies is from 3.8939 eV for the outermost electron in an atom of caesium to 11.567617 keV for the innermost electron in an atom of copper. Atomic level: Atomic binding energy The atomic binding energy of the atom is the energy required to disassemble an atom into free electrons and a ...
