The feature that identifies an atom as a specific element is the number of protons in its nucleus, known as the atomic number. Each element has a unique atomic number, which determines its chemical properties and its place in the Periodic Table. For example, hydrogen has one proton (atomic number 1), while carbon has six protons (atomic number 6). Thus, the atomic number is the defining characteristic that distinguishes one element from another.
