S8 P4 etc. H2SO4 is also a polyatomic molecule.
S8,p4,o3
polyatomic ionsFor example, ammonia, NH3, forms the polyatomic ion NH4+.
Examples: oxygen, sulfur, carbon, phosphorus etc.
You think probbable to diatomic molecules as O2, N2 or to the allotropes of P, S etc.
The word prefix poly- means many. So with the word polyatomic you have multiple atom types. So a polyatomic ion is an ion with multiple types of atoms in it. A polyatomic ion is composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in the context of acid and base chemistry or in the formation of salts.
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
Examples: HNO3, U3O8, K2SO4, NH4Cl, Al(OH)3 etc.
Ions made up of more than one atom are called polyatomic ions.
polyatomic ionsFor example, ammonia, NH3, forms the polyatomic ion NH4+.
structural formula
A molecule is neutral, an ion has an electrical charge.
They are molecules.No they are generally called molecules. However there are polyatomic ions that are charged molecules, such as SO42-
The general term is fairly straightforward, if you know a little Greek: polyatomic ions.
A molecule is a group of atoms bonded together. Hence, a molecule is only formed by 2 or more atoms. So, it could either be diatomic or polyatomic but not mono-atomic
11 atoms, 2 oatssium, 2 chromium, 7 oxygen. No molecules as such. 2 K+ and the polyatomic anion Cr2O72-.
Examples: oxygen, sulfur, carbon, phosphorus etc.
Ionic compounds contain ions, there are no neutral molecules. These are often charged atoms as in NaCl but may be polyatomic ions such as NH4+ which contains covalent bonds
