Valence bond theory — In chemistry, valence bond theory explains the nature of a chemical bond in a molecule in terms of atomic valencies. [Murrel, JN, Kettle, SF Tedder, JM The Chemical Bond , John Wiley Sons (1985) ISBN 0 471 90759 6] Valence bond theory summarizes… … Wikipedia
Atomic orbital — The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz. The colors show the wave function phase. These are graphs of ψ(x,y,z) functions which depend on the coordinates of one electron. To see the elongated shape of ψ(x,y,z)2… … Wikipedia
