How To: Calculate weight average atomic mass of an element

In Chemistry weight of some elements are measure in the form of Average Atomic Mass. Isotopes are found in different abundances in nature. Certain elements have many isotopes and certain elements have few isotopes. Regardless of the number of the natural isotopes, the weighted average mass takes into consideration not only the mass of each isotope, but what also its natural abundance in terms of percent as found in the nature. So when you have the mass of two isotopes of an element and are gi...

How To: Calculate weighted atomic mass

This video is about Level 2 atomic concepts, specifically the Pennium Lab. This helps you understand how atomic masses are derived for the periodic table. This teacher demonstrates how to do the calculation. He first reviews the Isotopes as they are different masses of the same type of atoms. He uses chromium as his example. It has a different number of neutrons in the nucleus. Using the equation, it could have either 26, 28, 29 or 30, with its 24 protons. So he subtracts the atomic number fr...
