Verified step by step guidance1
Understand the question: It asks for the smallest unit of an element that retains its chemical properties.
Recall definitions: A proton is a subatomic particle found in the nucleus, but it alone does not represent the element's chemical properties.
Recall definitions: An electron is a subatomic particle orbiting the nucleus, but it also does not represent the element's chemical properties by itself.
Recall definitions: A molecule is made up of two or more atoms bonded together, so it is not the smallest unit of an element.
Identify the correct answer: An atom is the smallest unit of an element that retains all the chemical properties of that element.
