Structure of the Atom

Structure of the Atom describes the quantum-mechanical model of the atom, which explains the fundamental nature of energy and matter, in terms of how electrons are arranged within atoms and how that arrangement determines the ultimate chemical and physical properties of elements. A discussion of atomic spectra, the Bohr model of the hydrogen atom, and the quantum numbers of an atomic orbital is provided. Other topics include the determination of quantum numbers from energy levels, the shapes of atomic orbitals, electron filling order, and the determination of the complete electron configuration of the elements.
