Correct answer: the smallest unit of matter that maintains its chemical identity.

Explanation: An atom is the basic unit of an element that retains its chemical properties. It is made of protons, neutrons and electrons (so it is not smaller than an electron — electrons are subatomic particles). The smallest unit of life is a cell, and the smallest unit of a compound that retains chemical identity is typically a molecule.
