= Frost diagram
{wiki=Frost_diagram}
A Frost diagram, also known as a Frost circle or Frost plot, is a graphical representation used in inorganic chemistry to show the stability of different oxidation states of elements, particularly transition metals. The diagram is named after the chemist A. A. Frost, who developed this method. In a Frost diagram, the oxidation states of an element are plotted on the vertical axis, while the standard electrode potential (often in volts) is plotted on the horizontal axis.
