Explanation: There are two properties that can be used to identify an element: the atomic number or the number of protons in an atom. The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question.

What part of the atom identifies the element?

Thus, the atomic number, which is the number of protons in the nucleus of the atom, identifies the element. Because an atom usually has the same number of electrons as protons, the atomic number identifies the usual number of electrons as well.

What is an element identify one example?

This means that all atoms that make up the element would have the same number of protons. For example, carbon is an element comprised of atoms having the same number of protons, i.e. 6. Common examples of elements are iron, copper, silver, gold, hydrogen, carbon, nitrogen, and oxygen.
