what is polymatic ion
Answers
A molecular ion is a covalently bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. Unlike a molecule, which has a net charge of zero, this chemical species is an ion.
The term poly means many, so a polyatomic ion is an ion that contains more than one atom. Thus it is different from monatomic ions, which contain only one atom. Examples of monatomic ions include Na+ and Cl- etc. This article will give details of polyatomic ions and their examples.
polyatomic ions
Definition of Polyatomic Ions
Polyatomic ions are covalently bonded groups of atoms and having a positive or negative charge caused by the formation of an ionic bond with another ion. Compounds formed from such a combination of ions are polyatomic ionic compounds.
But the polyatomic ion will behave as a single unit. In addition, polyatomic ions and those ionic compounds take part in chemical reactions such as acid-base, precipitation, and displacement similar to monatomic metallic ions.
They easily dissolve in water and conduct electricity and dissociate in a solution similar to other ions. Whereas they behave externally like monatomic ions, but their internal structure is more complicated. This is because there are two or more atoms present in the polyatomic ion
