The prefix alio means different.Two aliovalent ions are ions that have a different valence.In other words they don't have the same number of valence electrons. The converse of this word would be isovalent, meaning that the two ions are of the same valence.xists and is an alternate of. Merge this question into. Split and merge into it. Answer by Milobar.

Covalent compunds: write the element with a subscript that corresponds to the prefix. For example, carbon tetraiodide... Carbon is a nonmetal, and iodide is a nonmetal; therefore, carbon and iodide form a covalent compound. Thus, the covalent molecule nomenclature rules are used. Carbon is C, idodide is I, and tetra means 4, so. carbon tetraiodide is CI4. (hint: For our purposes, only covalent compounds use prefixes; therefore, the presence of a prefix means the compound must be covalent.) Acids: add as many protons (H+) as needed to cancel the charge of the anion.
