In chemistry and physics, the atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom. It is conventionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an atom of neutral charge, atomic number is equal to the number of electrons.
The atomic number Z should not be confused with the mass number A, which is the total number of protons and neutrons in the nucleus of an atom.

Quick question: Shouldn't the Mass Number include electrons ?
I searched for that but I couldn't find the answer. You could ask that question on blurtit I mean to all blurters here.
Atoms have tree sub-particles namely electron, proton and neutron. Atomic number of an element is the number of electrons and protons present in the atom of that element. Remember that proton no. And neutron no. Are always same in an atom but not in an ion. For example, atomic number of Carbon is 6. Elements can be distinguished by their atomic numbers
