Identify each of the following:

Solution 10QPStep 1 of 2:The goal of the problem is to identify given elements.Isotopes are the atoms that have the same atomic number but different mass number. That is the same number of protons but a different number of neutrons. Because there are a different number of neutrons, atoms exhibit different physical properties. We represent isotopes as : or X-AWhere ‘A’ represents mass number ‘Z’ represents Atomic number ‘X’ represents the chemical element.________________
