How can you tell one element is different from another?

The number of protons gives the atomic number. We know that every chemical element has its own atomic number. Thus, the atom of one element differs from another element's atom by the number of protons.

How do you determine the identity of an element is determined by?

An element is uniquely identified only by number of protons it contains the number of neutrons and electrons can vary without identity of element changing.

What particle is the best way to identify an element?

The Number of Protons Define the Nature of the Elements

The identity of an element is defined by Z, the number of protons in the nucleus of an atom of the element, which is different for each element.
