How many types of atom are contained in an element?
Answer: An element consists of only one type of atom. Each element on the periodic table is characterized by a unique type of atom.
For example, the element hydrogen (H) consists of only hydrogen atoms, the element oxygen (O) consists of only oxygen atoms, and so on. Each atom of a specific element has the same number of protons in its nucleus, which distinguishes it from atoms of other elements.
