Ionic Compounds Containing Polyatomic Ions. Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.

A monatomic ion consists of a single atom that is ionized. For example Na+, Cl-, Fe+3, O-2. A polyatomic ion consists of several atoms bonded to each other, but acting as if it were one ion. ClO3-, NH3+, SO4-2, CO3-2.

Polyatomic ions: Those ions which are formed from groups of joined atoms are called polyatomic ions. Compound ions are also called polyatomic ions. For e.g. Ammonium ion NH4+, is a compound ion which is made up of two types of atoms joined together nitrogen and hydrogen.

In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 ammonium ions to balance the one -2 sulfate ion. This will make the formula for Ammonium Sulfate (NH4)2SO4 .

Explanation: Detergents and soaps, the salts of long chain fatty acids are probably the best examples. These are certainly polyatomic. Of course, in the kitchen we commonly use bicarbonate of soda, NaHCO3 , (and other salts) as a raising agent.

Polyatomic ions are ions that are made up of two or more atoms held together by covalent bonds. Polyatomic ions can join with other polyatomic ions or elemental ions to form ionic compounds.

We write the sodium ion as Na+1. Aluminate is a polyatomic ion, which is an ion composed of multiple elements. Aluminate contains one aluminum atom and two oxygen atoms.

An ionic compound is named first by its cation and then by its anion. ... If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. The polyatomic ion name stays the same.

However, some elements are capable of forming both cations and anions given the right conditions. One example is hydrogen, which may gain (H-) or lose (H+) an electron, forming hydride compounds such as ZnH2 (where it is an anion) and hydron compounds such as H2O (where it is a cation).

['Ions form from elements when they gain or lose an electron causing the number of protons to be unequal to the number of electrons, resulting in a net charge.', 'If there are more electrons than protons (from an element gaining one or more electrons), the ion is negatively charged and called an anion.']

What are the similarities and differences between polyatomic ions and monatomic ions? Both carry a charge. A polyatomic ion is composed of more than one atom; a monatomic ion is a single atom.
