Polyatomic ion definition: A polyatomic ion is anioncomposed of two or moreatoms. A polyatomic ion has either a positive charge (cation) or negative charge (anion). Examples:The hydroxide cation (OH-) and the phosphate cation (PO43-) are bothpolyatomic ions....

If an ion consists of a single atom, it is called a monatomic ion. An example is the hydrogen ion, H+. By contrast, polyatomic ions, also called molecular ions, consist of two or more atoms. An example of a polyatomic ion is the dichromate anion: Cr2O72-...
atoms that have lost electrons to or gained electrons from other atoms. Ions are not neutral because the number of protons does not equal the number of electrons. Two or more atoms bonded to each other can also carry an overall positive or negative charge and these are calledpolyatomic ions....
Each ion becomes surrounded by solvent molecules, as shown in the diagram. Solvation of ionic compounds in polar solvents is driven by a decrease in free energy. Na+ Solvation Shell When NaCl dissolves in water, the polar water molecules form solvation shells around the dissolved ions. Here...
Cations have a positive charge, and this electrical charge changes their input in chemical reactions. What are some examples of cations? Examples of cations abound. Acetylcholine is a cation that is a neurotransmitter, responsible for the transference of nerve impulses. Potassium cations are common ...
Based on the number of atoms involved, ions are of two types: Consisting of a single atom:MONOATOMIC ION(an ion made of a single atom) Consisting of two or more atoms:POLYATOMIC ION / MOLECULAR ION Figure 2: Difference between monoatomic and polyatomic ion formula and monoatomic and polyat...
Polyatomic ions Sometimes multiple atoms come together to form a larger charged particle called a polyatomic ion. In their charged state, they act in much the same way as normal ions, but they are composed of multiple atoms. However, many polyatomic ions are created by a neutral species gainin...
