An element contains no protiens. An element is made of only one type of atom. Protiens are made up of elements.
A chemical element contain only atoms of this element (sometimes different from the mass number because many have isotopes).
Elements that contain only one type of atom are called pure elements or monatomic elements. For example, helium (He), neon (Ne), and oxygen (O) are pure elements because they consist of only one type of atom in their chemical structure.
