What is another name for polyatomic ion?
What is another name for polyatomic ion?
molecular ion
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.
What are polyatomic ions one word?
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.
What are polyatomic ions in short form?
The term poly means many, so a polyatomic ion is an ion that contains more than one atom. Examples of monatomic ions include Na+ and Cl- etc. …
Why are polyatomic ions not called molecules?
BRIAN M. Polyatomic ions contain two or more atoms bonded together in a manner that there is still a charge on the molecule.
What do you understand by polyatomic?
Definition of polyatomic : containing more than one and especially more than two atoms polyatomic molecules.
What do you mean by polyatomic molecules?
Polyatomic molecules are electrically neutral groups of three or more atoms held together by covalent bonds.
What is the difference between ionic compounds and polyatomic ions?
What is the difference between a polyatomic ion and an ionic compound? The most basic difference is that a polyatomic ion is a cluster of atoms with a net charge. An ionic compound is electrically neutral (no net charge).
Why are there 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.
What are common polyatomic ions?
| Symbols and Names of Some Common Polyatomic Ions and One Molecule | ||
|---|---|---|
| NH4+ | ammonium ion | cyanide ion |
| PO43- | phosphate ion | thiosulfate ion |
| HPO42- | hydrogen phosphate | mercury(I) ion |
| H2PO4- | dihydrogen phosphate | hydronium ion |
What is the difference between polyatomic ions and compounds?
Monatomic ions are composed of a single atom whereas polyatomic ions are composed of two or more atoms per ion. These ions can be either cations or anions. Both monatomic and polyatomic ions can form ionic compounds by having electrostatic attractions with the ions of opposite electrical charge.
Which of these is the best definition of a polyatomic ion?
A polyatomic ion, also known as a molecular ion, is a charged chemical species 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 statements describe polyatomic ions?
A polyatomic ion is a charged particle which has two or more atoms held together by covalent (sharing of pairs of electrons) bonds Some rules: 1. Ions that end in ate have oxygen in them. 2. Elements in the same family make similar ions.
Which polyatomic ions has a positive charge?
The most common types of ternary compounds consist of a metallic cation (positive ion) and a polyatomic anion (negative ion). The only common polyatomic ion with a positive charge is the ammonium ion.
