2r (rc) is the laplacian value of electron density, the 2r (rc) value less than zero means a covalent bond, the smaller the 2r (rc) value, the stronger of the covalence of the bond; the 2r(rc) alue larger than zero means a ionic bond, the larger the 2r(rc) value, the stronger of the ionic nature of the bond; if the 2r(rc) value is close to zero, it means a weak bond.
