So how come it doesn't say exactly 12 on the periodic table? Because there's more than one kind of carbon. In this video, we work through two examples of determining the average atomic mass for an element - which is a weighted average of all the different isotopes of that element. You can click on the links below to jump to sections in the lesson: 0:00 What is Average Atomic Mass 2:27 Example 1: average atomic mass of carbon 5:34 Example 2: average atomic mass of oxygen In this video, we refer to the definition of an isotope. If you need a quick refresher, here is our very short (under 1min) definition from our chemistry glossary: http://bit.ly/2hPTqPO This is a collection of SUPER FAST definitions.
