The nuclide isotope notation represents the isotope by its chemical symbol preceded by a superscript (to the left of the chemical symbol) showing the mass number and a subscript (also the the left of the chemical symbol) showing the atomic number (number of protons).

Copper-70:

• Chemical symbol: Cu
• Mass number: 70
• Atomic number: 29 (the atomic number is found in any periodic table)

Nuclide notation:

•            $^{70}_{29}Cu$
