WebOct 19, 2024 · Trivalent Cations are the positively charged ions having their valency (3+). It means divalent ions are formed by losing three valence electrons and attaining a positive charge. The cation is denoted by superscript 3+ on the symbol of atom or group of atoms. Some of the examples of trivalent cations are Aluminium (Al 3+ ), Chromium (Cr 3+ ), etc. WebDescription. The combining capacity, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.Chlorine, as it has a valence of one, can …
