Discussion sur les propriétés générales. "
There is some controversy about the classification of the elements on the boundary between the main group and transition-metal elements on the right side of the table. Il est suivi d’un chapitre par groupes. Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration. Très fortement électropositifs, les éléments de transition sont des réducteurs puissants qui réagissent facilement avec la plupart des agents chimiques. Transition Metals vs. Main-Group Elements . La chimie des éléments de transition s'avère très riche puisqu'elle englobe la chimie de coordination et la chimie du solide. The elements in question are zinc (Zn), cadmium (Cd), and mercury (Hg). Greenwood, A. Earnshaw, Chemistry of the Elements, 2nd edition, Butterworth-Heinemann, Oxford, UK, 2001.
Transition Metal Ions Transition metals belong to the d block, meaning that the d sublevel of electrons is in the process of being filled with up to ten electrons. Sc, Ti, V, Cr, ... N.N.
Most transition elements react slowly, or not at all, with oxygen at room temperature. The transition elements share some physical properties. The group 1 elements react quickly with oxygen in the air at room temperature.
