formal charge


formal charge
Formal chargeFormal charge is the charge an atom in a molecule would have if all electrons in bonds were shared equally between the two bonded atoms. To calculate formal charge, take the number of valence electrons for an atom and subtract half the number of bonding electrons and the total number of electrons in lone pairs for the same atom in a molecule; the result indicates which atoms are more negative and which more positive, which is useful for predicting where in a molecule reactions will occur. is the charge an atom in a moleculeA set of atoms joined by covalent bonds and having no net charge. would have if all electrons in bonds were shared equally between the two bonded atomsThe smallest particle of an element that can be involved in chemical combination with another element; an atom consists of protons and neutrons in a tiny, very dense nucleus, surrounded by electrons, which occupy most of its volume..
