Question

2. An atom is a smallest unit of matter, which has an independent existence and can retain complete physical and chemical properties.

• A. True
• B. False

Answer 1

The correct option is B False

• The smallest unit of an element is defined as the atom, which may or may not have its own existence but always participates in a chemical reaction.
• A molecule is the smallest unit of matter with its own existence and the ability to preserve all of matter's physical and chemical features.
• Therefore, a molecule is the smallest unit that has its own existence and exhibits all of the qualities of the substance.

Hence the given statement is false.
