Which of the following best defines a molecule?

A. The smallest particle of matter
B. The smallest particle having the same property of the matter
C. The smallest particle having properties of all substances
D. The smallest particle having mixed property of matter



Answer :

Final answer:

A molecule is the smallest particle retaining the properties of a compound, consisting of two or more atoms bonded together.


Explanation:

A molecule is the smallest particle of a specific compound that retains the chemical properties of that compound; it consists of two or more atoms bonded together.

Even our most familiar solids are mostly space. If we could take apart such a solid, piece by piece, we would eventually reach the tiny molecules from which it is formed. Molecules are the smallest particles into which any matter can be divided while still retaining its chemical properties. For instance, a molecule of water (H₂O) consists of two hydrogen atoms and one oxygen atom bonded together.

Atoms combine to form molecules, which then interact to form solids, gases, or liquids. A molecule represents a discrete combination of atoms. Understanding molecules is essential in grasping the properties and behavior of matter.
