WebbQuantum Numbers to Orbitals. Chemists recognise s, p, d & f atomic orbitals. Their topologies (shape, phase) and electron occupancy are described by four quantum numbers: n. The principal quantum number. ℓ. The subsidiary or azimuthal or angular momentum or orbital shape quantum number. mℓ. The magnetic quantum number. The periodic table, also known as the periodic table of the (chemical) elements, is a rows and columns arrangement of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry. It is a graphic formulation of the periodic law, which states that the properties of the chemical elements exhibit an approximate periodic dependen…
