What Does the Atomic Number Represent?

The atomic number is the number of protons in the nucleus of an atom

nucleus of an atom
The nucleus of an atom consists of neutrons and protons, which in turn are the manifestation of more elementary particles, called quarks, that are held in association by the nuclear strong force in certain stable combinations of hadrons, called baryons.

. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).

What 3 things does the atomic number tell you?

The three main atomic particles are protons, neutrons and electrons. The atomic number of an atom identifies the number of protons in the atom. This is the defining characteristic of an element.

Does the atomic number represent electrons?

The number of protons in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom). Thus, all atoms that have the same number of protons--the atomic number--are atoms of the same element.
