Webunderstanding of chemical bonding he moved to Cambridge, initially focusing on teacher education, but increasingly working with higher degree students. He was the Royal Society of Chemistry’s Teacher Fellow in 2000-2001. His main research interests relate to aspects of conceptual learning in science – including issues of Webvalence bond theory: a covalent bond forms between the two atoms by the overlap of half-filled valence atomic orbitals from each atom. In chemistry, valence bond (VB) theory is one of two basic theories—along with molecular orbital (MO) theory—that use quantum mechanics to explain chemical bonding.

Covalent Bonds. Lewis' second great idea was this: two atoms attract each other (create a covalent bond) by sharing a pair of electrons. Lewis claimed that the shared electrons became part of each atom's electron configuration, so sharing effectively boosts each atom's electron count. mount sinai flatbush
