A term referring to the atomic radius, one-half the distance between nuclei of identical bonded elements.
Atomic Size
The tendency of a species not to be attracted by a magnetic field as a result of its electrons being paired.
The energy change accompanying one mole of electrons being added to one mole of gaseous atoms or ions.
Electron Affinity
A principle stating that when orbitals of equal energy are available, the electron configuration of lowest energy has the maximum number of unpaired electrons with parallel spins.
Hund's Rule
Electrons that fill all the energy levels of an atom except the valence level; electrons also present in atoms of the previous noble gas and any completed transition series.
Inner Electrons
The energy required to remove completely one mole of electrons from one mole of gaseous atoms or ions.
Ionization energy
A depiction of electron number and spin in an atom's orbitals by means of arrows in a series of small boxes, lines, or circles.
Orbital Diagram
The tendency of a species with unpaired electrons to be attracted by an external magnetic field.
The electrons involved in compound formation; in main-group elements, the electrons in the outer level(shell).
Valence Electrons
