Chemistry notes test one Organic chemistry: study of carbon compounds Rules of Electron ground state configuration • • • Orbitals fill in order of increasing energy, low to high Each orbital can hold up to two electrons When orbitals of equivalent energy are available, one electron is added to each equivalent orbital before a second is added to any of them EX: Oxygen 1s2 2s2 2px2 2py12pz1 When a species has a charge, for example, (2-) then on the periodic table, go back two spaces. When the species has the charge (2+) go forward two spaces. Ionic Bonding: formed by the transfer of electrons from the valence shell of an atom of lower electronegativity to the valence shell of an atom of higher electronegativity. More electronegative becomes an anion and the less electronegative becomes a cation. EX: Na* + F --> Na+ + FPolar Bonds: There is a difference in electronegativity Nonpolar: The electronegativity, when subtracted, is zero. Covalent bond: Shares Electrons The sigma negative sign goes on the molecu...
