Positive ions: Na +, K +, Ca2+, Al 3+ These chemistry flashcards contain 65 of the most common monatomic and polyatomic ions. The name of a monatomic anion consists of the stem of the element name, the suffix -ide, and then the word ion.Thus, as we have already seen, Cl − is “chlor-” + “-ide ion,” or the chloride ion. magnesium. The tables below list common polyatomic ions that you will be using throughout this General-Chemistry laboratory series (Chem 151-152). [1] For example, calcium carbonate consists of the monatomic ion Ca2+ and the polyatomic ion CO32−. NH4 +ammonium H3O. sulfur fluorine potassium . *The ammonium ion will combine with any cation.
