WebThe loss of four electrons by either a carbon atom or a silicon atom to give ions having a positive charge of four (or +4, written C 4+ or Si 4+) with the electron configurations of the preceding noble-gas atoms is precluded by the sizable ionization energies. Like other groups, the members of this family show patterns in their electron configurations, especially the outermost shells, resulting in trends in chemical behavior. Most of the chemistry has been observed only for the first three members of the group; chemical properties of rutherfordium are not well-characterized, but what is known and predicted matches its position as a heavier homolog of hafnium.
