Abstract
In this paper a tertative approach is made to explain the phase transition that occurs at the boundary of the inner core of the earth. A MODEL for the electronic configuration is introduced to explain the transition from the liquid state of the outer core to the solid state of the inner core. It is proposed that the Electrons of the outermost orbitals of the iron atoms jump to the conduction band leaving smaller and electrically stranger ions behind. This MODEL provides a simple and straightforward explanation to the liquid-to-solid transition and suggests that the electrical conductivity must be higher in the inner core than in the outer core.
