Answer 2

1.) Atom refers to the smallest constituent unit of a chemical element. Molecules refer to a group of two or more atoms that are held together due to chemical bonds.

2.) i) Atom refers to the tiniest particle of an element or compound that is not visible to naked eye. Furthermore, it may or may not exist independently. Besides, it is made up of the nucleus (protons and neutrons) and electrons. Moreover, it has a spherical shape.

ii)Molecule refers to the set of two or more atoms that come together by a bond. Furthermore, they indicate the smallest component of a compound. In addition, they exist in a free state. Also, they comprise two or more identical or non-identical atoms bonded chemically.
