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! :) )

Make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries. Wow, that’s a mouthful! Do you think there could be anything smaller?
