Question

Distinguish between the following terms.
a molecule versus ion
b. covalent bonding versus ionic bonding
c. molecule versus compound
d. anion versus cation

Short answer

Distinguish between these elements were discussed.

Step-by-step solution

Distinguish between Molecule and ion

Molecule	Ion
The collection of two or more atoms with different or same elements	The group of atoms have net negative or positive charge
Examples includes Hydrogen, Methane, Water etc.,	Examples of Ions are Na+ and Cl-

Distinguish between Molecule and ion

Covalent bonding	Ionic bonding
It can be defined as the electrostatic attraction between opposite ions in charge.	In ionic bonding, the electrons are shared by atoms.
Example is sodium chloride (NaCl)	Example is Hydrochloric acid (HCl)

Distinguish between Molecule and Compound

Molecule	Compound
The collection of two or more atoms with different or same elements	Compounds have constant separation in which it can be broke into elements using some chemical process.
Examples includes Hydrogen and nitrogen	Examples of Compounds are Glucose and Water

Distinguish between Anion and Cation

Anion	Cation
It is a negative ion	It is a positive ion
When there is an addition of electron in neutral atom, it becomes anion	When there is a loss of electron in neutral atom, it becomes cation.
