The hydroxide ion consists of an oxygen atom bonded to a hydrogen atom, and it carries a negative charge.<\/li>\n\n\n\n<li><strong>NH4I<\/strong>: Ammonium iodide contains the ammonium ion (NH4\u207a), which is a polyatomic ion. The ammonium ion is composed of a nitrogen atom bonded to four hydrogen atoms, carrying a positive charge. The anion in this case is the iodide ion (I\u207b), which is a monatomic ion, not a polyatomic ion, but the ammonium ion qualifies this compound as containing a polyatomic ion.<\/li>\n\n\n\n<li><strong>NaBrO4<\/strong>: Sodium perbromate is composed of the sodium ion (Na\u207a) and the perbromate ion (BrO4\u207b), which is a polyatomic ion. The perbromate ion contains a bromine atom bonded to four oxygen atoms, carrying a negative charge.<\/li>\n\n\n\n<li><strong>Fe(OH)3<\/strong>: Iron(III) hydroxide consists of the iron ion (Fe\u00b3\u207a) and the hydroxide ion (OH\u207b). The hydroxide ion is a polyatomic ion, and the compound is often used as a precipitate in chemical reactions.<\/li>\n<\/ol>\n\n\n\n<p>In summary, a polyatomic ion is an ion made up of two or more atoms that are covalently bonded together, but the entire group carries a charge. In the compounds listed, the hydroxide (OH\u207b), ammonium (NH4\u207a), and perbromate (BrO4\u207b) ions are all polyatomic ions, while the other ions are monatomic (e.g., iodide I\u207b, bromide Br\u207b).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Name each ionic compound containing a polyatomic ion. a.
