How do you read isotope symbols?
Isotope Notation
Isotopes can also be defined in standard, or “AZE”, notation where A is the mass number, Z is the atomic number, and E is the element symbol. The mass number “A” is indicated with a superscript to the left of the chemical symbol “E” while the atomic number “Z” is indicated with a subscript.
