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. • SUBSCRIBE so you never miss a video! • http://bit.ly/SocraticaSubscribe • MORE Chemistry content on our website • https://www.socratica.com/subject/che... • ⬣⬣⬣ • SUPPORT our channel: • Patreon : / socratica • PayPal donation: https://www.paypal.me/socratica • Bitcoin : bc1qda47tgfyk67lxa7yqn8y5m02hjcglghsd5c58n • Thank you! • ⬣⬣⬣ • RECOMMENDED Books Resources: • Socratica Practice Tests: https://shop.socratica.com/collection... • How to Be a Great Student: https://amzn.to/3t5jeH3 • 239 pc Chemistry Molecules Model Kit: https://amzn.to/3DhlG3n • Brown and LeMay Chemistry: The Central Science • 14th edition: https://amzn.to/3fiLR1G • McGraw/Hill Chemistry by Chang Goldsby https://amzn.to/3UclbP3 • Uncle Tungsten: Memories of a Chemical Boyhood by Oliver Sacks https://amzn.to/3ffeRau • Napoleon's Buttons: How 17 Molecules Changed History https://amzn.to/3sIXuBW • ⬣⬣⬣ • Written and Produced by Kimberly Hatch Harrison • About our instructor: • Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years.
