Which symbols represent atoms of the same element that are istopes?

The normal chemical symbol is used for the isotope with the addition of the atomic number (Z) at the lower left of the symbol and the atomic mass number (A) at the upper left as shown X.For example Li and Li represent two isotopes of lithium.Since all lithium isotopes have an atomic number Z=3, this number is usually omitted and the isotopes are represented by the symbols Li and Li. These are sometimes written as Lithium-6 and Lithium-7 or Li-6 and Li-7.
