Atomic number: The number of protons in an atom. Relative atomic mass (Ar): The average mass of an atom compared to 1/12th the mass of carbon-12.
Atom is uniquely identified with the atomic number (symbol Z). The atomic number is the number of protons present in the nucleus. In case of uncharged atoms, the atomic number is equal to the number of the electrons. In contrast, in ions, the number of electrons is the difference between the atomic number and the charge of ions.
Atomic charge = number of protons − number of electrons. As will be discussed in more detail later For example, a neutral sodium atom (Z = 11) has 11 electrons. If this atom loses one electron, it will...
