An important feature of this model is that qualitative predictions about deviations from ideal shapes can be made on the basis of differences in the sizes of the domains involved.

Developed by Gillespie and Nyholm based on proposals by Sidgwick and Powell, its basic postulate is that the region of space occupied by a pair of electrons can be approximately represented by a sphere, with the preferred arrangements of pairs those in which the spheres are closely packed around the core of the atom. A simple method for predicting the arrangements of bonds around an atom in a covament molecule, FTP, what is this model with a five-letter acronym?
