  2. Electrochemistry - Wikipedia

    en.wikipedia.org/wiki/Electrochemistry

    This type of cell will generate a potential that can be predicted by the Nernst equation. Both can undergo the same chemistry (although the reaction proceeds in reverse at the anode) Cu 2+ (aq) + 2 e − → Cu(s) Le Chatelier's principle indicates that the reaction is more favorable to reduction as the concentration of Cu 2+ ions increases ...

  3. Arrow pushing - Wikipedia

    en.wikipedia.org/wiki/Arrow_pushing

    Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.

  4. Electron configuration - Wikipedia

    en.wikipedia.org/wiki/Electron_configuration

    In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6 , meaning that the 1s, 2s, and 2p subshells are occupied by two, two, and six ...

  5. Electron - Wikipedia

    en.wikipedia.org/wiki/Electron

    A 1906 proposal to change to electrion failed because Hendrik Lorentz preferred to keep electron. [25] [26] The word electron is a combination of the words electric and ion. [27] The suffix -on which is now used to designate other subatomic particles, such as a proton or neutron, is in turn derived from electron. [28] [29]

  6. Molecular Hamiltonian - Wikipedia

    en.wikipedia.org/wiki/Molecular_Hamiltonian

    The stationary nuclei enter the problem only as generators of an electric potential in which the electrons move in a quantum mechanical way. Within this framework the molecular Hamiltonian has been simplified to the so-called clamped nucleus Hamiltonian , also called electronic Hamiltonian , that acts only on functions of the electronic ...

  7. Ab initio quantum chemistry methods - Wikipedia

    en.wikipedia.org/wiki/Ab_initio_quantum...

    Ab initio quantum chemistry methods are a class of computational chemistry techniques based on quantum chemistry that aim to solve the electronic Schrödinger equation. [1] Ab initio means "from first principles" or "from the beginning", meaning using only physical constants [2] and the positions and number of electrons in the system as input.

  8. Electrochemical potential - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_potential

    In electrochemistry, the electrochemical potential of electrons (or any other species) is the total potential, including both the (internal, nonelectrical) chemical potential and the electric potential, and is by definition constant across a device in equilibrium, whereas the chemical potential of electrons is equal to the electrochemical ...

  9. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    It has uses in determining possible electron re-configuration when referring to reaction mechanisms, and often results in the same sign as the partial charge of the atom, with exceptions. In general, the formal charge of an atom can be calculated using the following formula, assuming non-standard definitions for the markup used:
