The relation between the ground-state energy and the one-body virial is discussed. Using a result of Levy and Perdew, the exchange energy, the correlation contribution to the kinetic energy and the correlation energy are also related to the one-body virial and contribution written explicitly in terms of the density. The sum of the orbital energies is likewise expressed.
