In atomic physics, a partial charge (or net atomic charge) is a non-integer charge value when measured in elementary charge units. It is represented by the Greek lowercase delta (𝛿), namely 𝛿− or 𝛿+. Partial charges are created due to the asymmetric distribution of electrons in chemical bonds. For example, in a … See more

1916Gilbert N. Lewis introduces the concept of partial charge in his book The Atom and the Molecule.1934Linus Pauling proposes the concept of electronegativity, which is related to the tendency of atoms to attract electrons and form partial charges.1955Robert S. Mulliken develops the Mulliken population analysis, a method to calculate partial charges from molecular wave functions.1977Richard F.W. Bader introduces the atoms in molecules analysis, a method to partition the electron density into atomic basins and assign partial charges.1988Christopher J. Cramer and Kim K. Baldridge propose the natural population analysis, a method to calculate partial charges from natural atomic orbitals.1993Jay W. Ponder and Frederick M. Richards develop the RESP method, a method to fit partial charges to reproduce the electrostatic potential of molecules.2016Thomas A. Manz and Andreas W. Götz develop the DDEC method, a method to compute partial charges that reproduce both the chemical states and the electrostatic potential of materials.Wikipedia text under CC-BY-SA license 5.10: Electronegativity and Bond Polarity - Chemistry LibreTexts

6.4 Polarity of Molecules | Introductory Chemistry - Lumen Learning
- As discussed previously, polar covalent bonds connect two atoms with differing electronegativities, leaving one atom with a partial positive charge (Δ+) and the other atom with a partial negative charge (Δ–), as the electrons are pulled toward the more electronegative atom. This separation of charge gives rise to a bond dipole moment. The magnitude...
