Understand the question: It asks for the smallest part of an element that still retains the chemical properties of that element.
Recall definitions: A proton is a subatomic particle found in the nucleus of an atom, but it alone does not retain chemical properties.
Recall definitions: An electron is a subatomic particle orbiting the nucleus, but it also does not retain the chemical properties of the element by itself.
Recall definitions: A molecule is a group of atoms bonded together and can be made of one or more elements, so it is not the smallest part of a single element.
Identify the correct answer: The atom is the smallest unit of an element that retains all the chemical properties of that element.
