Final answer:

The atomic number defines an element's identity by representing the number of protons in the nucleus and the relationship between protons and electrons.


Explanation:

The atomic number of an element defines the identity of the atom as it indicates the number of protons in the nucleus. For example, carbon always has an atomic number of 6. In a neutral atom, the number of protons equals the number of electrons. The number of neutrons can be calculated by subtracting the atomic number from the mass number.
