EVERYDAY SCIENCE

Detailed explanation-1: -Physical chemists are focused on understanding the physical properties of atoms and molecules, the way chemical reactions work, and what these properties reveal.

Detailed explanation-2: -Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.

Detailed explanation-3: -A tiny particle of a chemical element is called an atom, which may or may not exist independently. Molecules refer to the group of atoms that the bond binds together, representing the smallest unit in a compound. Two or more identical or distinct atoms are chemically bonded.

Detailed explanation-4: -Chemistry focuses on matter and energy at the scale of atoms and molecules. It is the study of the structure, properties, and interactions of matter. Important concepts in chemistry include physical changes such as liquids freezing and chemical reactions such as substances burning.
