If a stress (change of conditions) is applied to a system at equilibrium, the system shifts in the direction that reduces stress.

Chemical Equation

Valence Shell Electron Pair Repulsion Theory

Assumes that electron pairs are arranged around the central element of a molecule or polyatomic ion so that there is maximum separation (and minimum repulsion) among regions of high electron density.

 

Faraday

One faraday of electricity corresponds to the charge on 6.022 x 1023 electrons, or 96,487.301 coulombs.
