Confusing Elements and Atoms
Students often think that an element is the smallest part of matter, rather than understanding that an atom is the smallest part of an element that can exist.
Remember that an atom is the basic unit of an element, while an element is made up of one type of atom. Focus on the definitions and relationships between these concepts.
