Ellingham diagram - Wikipedia

An Ellingham diagram is a graph showing the temperature dependence of the stability for compounds. This analysis is usually used to evaluate the ease of reduction of metal oxides and sulfides.These diagrams were first constructed by Harold Ellingham in 1944. In metallurgy, the Ellingham diagram is used to predict the equilibrium temperature between a metal, its oxide, and oxygen — and by ...

Atom Diagrams: Electron Configurations of the Elements

It's easier to understand electron configuration and valence if you can actually see the electrons surrounding atoms. For that, we have electron shell diagrams. Here are electron shell atom diagrams for the elements, ordered by increasing atomic number. For each electron shell atom diagram, the element symbol is listed in the nucleus.
