To determine the atomic number of an atom, you can refer to the periodic table. Each element is assigned a unique atomic number, which represents the number of protons in the nucleus of an atom. Since atoms are electrically neutral, the number of protons is also equal to the number of electrons present in the atom. Therefore, the atomic number provides information about the basic structure of an atom and the number of charged particles it contains.
