The ions which contain more than one atoms behaving as a single unit are called polyatomic ions. For example, PO43−,CO32−
What are polyatomic ions give examples answer?
The prefix poly- means “many,” in Greek, but even ions of two atoms are commonly referred to as polyatomic. Examples: Carbonate (CO32-), sulphate (SO42-), nitrate – NO3- and hydroxide ions OH- are all polyatomic ions.
What are 3 examples of polyatomic ions?
Well-known examples of such polyatomic ions are the sulfate ion (SO42–), the hydroxide ion (OH–), the hydronium ion (H3O+), and the ammonium ion (NH4+).
What is a polyatomic ion Class 9?
Answer: Polyatomic ions are ions that contain more than one atom. Polyatomic ions are created when a number of atoms come together to form a group. It is held together by covalent bonds.
What are polyatomic ions Class 10?
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.
What are called polyatomic ions?
A polyatomic ion, also known as 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.
What are polyatomic ions give an example of polyatomic cation?
(a) A group of atoms carrying a charge is known as polyatomic ion, example of polyatomic cation: NH4+ and polyatomic anion: NO3-.
What are polyatomic ions give examples in Teachoo?

What are diatomic and polyatomic ions give examples?
These type of ions are molecules in which they are bonded with different atom are known as Polyatomic ions or molecules. Example -HCO−3, H3O+, OH− ,etc. Diatomic ion- These type of ions are molecules in which atoms are bonded with there same atom are known as diatomic ions . Example – N2, H2, O2 ,Br2, Cl2 ,etc.

What are polyatomic ions Ncert?
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.
Which is an example of a polyatomic ion quizlet?
Terms in this set (10) A polyatomic ion is a molecule (more than one atom) that has an electric charge. For example, the phosphate group shown has one phosphate, 4 oxygens and a -3 charge.
Why sulphate is an example of polyatomic ion?
Sulphate ion is represented as SO42- . It is clear from the formula that it is made up of sulphur and oxygen atoms. Hence, it is an example of polyatomic ion.
Why are polyatomic ions?
Polyatomic ions are covalently bonded groups of atoms with a positive or negative charge caused by the formation of an ionic bond with another ion. Compounds formed from such ion combinations are called polyatomic ionic compounds, but the polyatomic ion behaves as a single unit.
