What is the example of polyatomic ion?
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. Rule 1.
Why do all polyatomic ions have a charge?
Explanation: Polyatomic ions usually have a charge because the compound itself has either gained an extra electron (making the charge negative) or it has lost an electron (making the charge more positive). The most common polyatomic ions have negative charges.
Which is an example of a polyatomic ion?
Rules for Naming Ionic Compounds Containing Polyatomic Ions. Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO 3-, 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.
What kind of ion is composed of two atoms?
Polyatomic ion. A polyatomic ion, also known as a molecular ion, is a charged chemical species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit. The prefix poly-means “many,” in Greek, but even ions of two atoms are commonly referred to as polyatomic.
Which is an electrostatic potential map of the nitrate ion?
An electrostatic potential map of the nitrate ion (NO3−). A polyatomic ion, also known as a molecular ion, is a charged chemical species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit.
Which is an ion with a net charge of zero?
Unlike a molecule, which has a net charge of zero, this chemical species is an ion. (The prefix poly- carries the meaning “many” in Greek, but even ions of two atoms are commonly described as polyatomic.) In older literature, a polyatomic ion may instead be referred to as a radical (or less commonly, as a radical group ).
