A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...

VSEPR theory provides a practical way to predict the 3D shapes of molecules by focusing on how electron pairs repel each other. This model explains why atoms arrange in specific geometries, from ...

Electronegativity and molecular polarity are central to understanding chemical bonding. By combining periodic trends with molecular geometry, you can predict whether a molecule is polar or nonpolar.
