Molecular model - Wikipedia
WEBA molecular model is a physical model of an atomistic system that represents molecules and their processes. They play an important role in understanding chemistry and generating and testing hypotheses.
WEBLesson summary. molecular orbitals One model of molecular bonding pictures a molecular orbital that is a combination of individual atomic orbitals. A bonding orbital can be occupied by a pair of electrons. In a sigma ( σ) bond, the molecular orbital is symmetrical around the axis connecting two atomic nuclei.
