equilibrium condensation model

(chemical model explaining solar system planet abundances)

The equilibrium condensation model takes plausible values for the temperature and pressure profiles of the solar nebula and predicts the abundances of chemical elements of the individual planets based upon the temperature/pressure thresholds at which each element or compound would condense. It does well explaining many of the abundances, with a few exceptions, such as how Mercury can have elements that would support a magnetic field, and how the Earth came to have so much water. The model has been around for a while and is likely now considered an approximation, and current thoughts on planetary migration potentially affect its conclusions.
