Cations, Divalent. Divalent Cations . Positively charged atoms, radicals or groups of atoms with a valence of plus 2, which travel to the cathode or negative pole during electrolysis. . 0.80
Cations, Monovalent. Monovalent Cations . Positively charged atoms, radicals or group of atoms with a valence of plus 1, which travel to the cathode or negative pole during electrolysis. . 0.80
Ions 5743. An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS. . 0.54
Coordination Complexes. Metal Complexes . Complexes, Coordination . Complexes, Metal . Neutral or negatively charged ligands bonded to metal cations or neutral atoms. The number of ligand atoms to which the metal center is directly bonded is the metal cation's coordination number, and this number is always greater than the regular valence or oxidation number of the metal. A coordination complex can be negative, neutral, or positively charged. . 0.33
Sulfonium Compounds. Compounds, Sulfine . Compounds, Sulfonium . Sulfine Compounds . Sulfur compounds in which the sulfur atom is attached to three organic radicals and an electronegative element or radical. . 0.33
Photographs. Still images produced from radiation-sensitive materials (sensitive to light, electron beams, or nuclear radiation), generally by means of the chemical action of light on a sensitive film, paper, glass, or metal. Photographs may be positive or negative, opaque or transparent. . 0.31
