So what do you think the average atomic mass puppies is? :) Here’s the lecture from Monday on calculating the average atomic mass of isotopes. Isotopes, not puppies.

Did you know there is a baseball team called the Isotopes? No kidding, they’re a minor league team in Albuquerque, New Mexico. This is a pic of their “Isotope Field.” Go figure! Almost all elements have naturally occurring isotopes is some amount. Are you getting the hang of writing hyphen notation and nuclear symbols? We’ll finish working on calculating average atomic mass on Monday. Use the formula I gave you today to work those problems on the homework. How’s the carbon isotope project coming?

Can you believe atoms are that small – and neutron even waaaaaay smaller! Here’s another picture from the IBM Almaden Research Center of atoms. 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! (Oops, I did it again! :) )

Here’s the lecture on atomic numbers & isotopes. Practice writing and reading both types of nuclear symbols. And yes you can work average atomic mass problems! It’s basically just plug and play. Remember the relative atomic mass will be in amu or u. Hope you’re having a great weekend!
