Distinguish between atom,molecule and polyatomic ion
Answers
Answer:
A molecule, by definition, is a neutral substance. A glucose molecule, wait too complex, a coppler (II) sulfate (CuSO4) molecule is a neutral substance as both cations (positive, think caTs) and anion (negative, sounds similar to onion, which makes people cry) are in equal amount to each other.
The copper (II) ion has a charge of 2+ and the sulfate ion has a charge of 2-.
A polyatomic ion is literally an ion made of multiple atoms. It is unbalanced in its charge and can react to make itself stable.
Using the previous example, the sulfate (So4) ion is a polyatomic ion made up of 2 different atoms: sulfur and oxygen. The sulfur and the oxygen atoms bond covalently (2 non-metal atoms bonded together) to form the SO4 ion.

Answer:
here is ur answer dear
Polyatomic ions are formed by a combination of two or more atoms which are act as single atom during the reaction. As for example- hydroxide ion (OH-),nitrate ion(NO3-),sulphate ion(SO42-),bicarbonate ion(HCO3-) etc.
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. As for example-N2+,NO+,O2+,Ar2+,BaO+,BaOH+ etc.
