Molecular Geometry

Molecular Geometry. Bonding. Covalent bonds occur when atoms are at an ideal distance from one another. At this distance attractive forces predominate repulsive forces. Too close the atoms repel each other. Too far away they do not attract. Bonding. Polarity of Polyatomic Molecules.

Every electron on an atom is in a definite state (energy level) with a definite energy.

Quantum Theory. Every electron on an atom is in a definite state (energy level) with a definite energy. In order for an electron to change energy levels, a photon must be either absorbed or emitted, governed by ? E = hc/ ?
