Chemistry 4-6-21 Isotopes & Average Atomic Mass

CHEMISTRY: Isn’t God awesome to give us minds to understand the world around us – even the parts we can’t see!

Here’s the discussion for Tuesday on isotopes and average atomic mass. How are you doing on writing nuclear symbols? Also make sure you can use them to determine the number of protons, neutrons, electrons, etc., AND be sure you can use the formula to find average atomic mass!

Can you believe atoms are that small – and the nucleus even waaaaaay smaller! The thumbnail is a picture of atoms from the IBM Almaden Research Center. These are iron atoms on top of copper. Being able to move atoms around like this was a giant leap in the field of nanotechnology! (Sorry about that, bad pun! 🙂 )

  1. This week I’ve struggled with listening and paying attention in class while watching the lessons. To make sure I know all the information I need to, I will read over the chemistry textbook, rewatch the lessons, and pay extra attention in class for the rest of the week.

  2. Struggle: This week I struggled on Tuesday night’s homework. I was a little bit confused on the question with the graph. I went back to the Vodcast from Tuesday’s class and was able to fill It in. After re-watching that portion of the Vodcast I now understand the lesson a little bit more that before.
