Polyatomic ions.

The ions that we have discussed so far are called monatomic ions, that is, they are ions formed from only one atom. We also find many polyatomic ions. These ions, which act as discrete units, are a group of covalently-bonded atoms with an overall charge. Some of the more important polyatomic ions are listed in Table \(\PageIndex{1}\).Jul 13, 2017 · Jul 13, 2017. A polyatomic ion is a charged chemical species with more than one type of atom present. Polyatomic ions are used worldwide on a daily basis, some common ones being nitrate ( NO− 3 ), perchlorate ( ClO− 4 ), and ammonium ( NH+ 4 ). Polyatomic ion species often bond chemically with metals to create simple ionic compounds ... If more than one polyatomic ion is needed, its formula is written inside brackets. Example. Calcium hydroxide contains Ca 2+ and OH-ions: this is two positive charges and one negative charge;Thus we write the formula. Na+1 Cl+1 O−2 Na +1 Cl + 1 O − 2. if oxidation numbers are to be included. b) In this case the oxidation numbers must add to –1, the charge on the polyatomic ion. Since O is usually –2, we have. Oxidation number of Cl + 4(– 2) =– 1 Oxidation number of Cl + 4 ( – 2) = – 1.

For example, NO 3 − is the nitrate ion; it has one nitrogen atom and three oxygen atoms and an overall 1− charge. Table \(\PageIndex{1}\) lists the most common polyatomic ... If only one polyatomic ion is in a formula, parentheses are not used. As an example, the formula for calcium carbonate is \(\ce{CaCO_3}\). The carbonate ion carries a \(2-\) charge and so exactly balances the \(2+\) charge of the calcium ion. There are two polyatomic ions that produce unusual formulas.
