In the problem, we are looking for the atomic mass of chlorine. We know that the atomic number of an element is the same as the number of protons in that element. WebPSE explains: This is what the information about the element means (example oxygen) The elements are identified by a symbol (letter). ... All elements are stable up to lead (element 82), so there are no radioactive isotopes. Technetium (43) and 61 (Promethium) are exceptions. The PSE therefore shows 80 stable elements that occur naturally.
