The atomic number of an element is equal to the number of protons in the nucleus of its atom. The atomic number is also known as proton number of the element. Further, in an atom, number of protons is equal to the number of electrons. Hence, atomic number is also equal to the number of electrons in an atom of the element. Thus,
The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.
