Conversely, as the number of phases increase in the system, the variance of the system must correspondingly decrease. A corollary to Gibbs' Phase Rule is Goldschmidt's Mineralogical Phase Rule: for a given rock in equilibrium at a fixed P and T, the number of phases is less than or equal to the number of components.
All elements in nature are reactive chemically, except the Noble metals and the Noble gases. This is due to the fact that the electronic configurations of the atoms of all elements are not stable. A stable electronic configuration is one which follows the octet or the duplet (in Hydrogen and Helium) rule.
