Did it help? Just don’t forget the conversion factor, and think through the problems. Put units first and then numbers. Make sure what you’re doing has a reason and makes sense!

Here’s the lecture from Friday on using moles and Avagadro’s number to convert from moles to mass and atoms. Practice, practice, practice!

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!

By the way, the cover picture here is like the ones I showed you in class, but this is one of the first.

Scientists at the Alameden Research Center at IBM really wowed the scientific community when they were able to arrange xenon atoms in the shape of “IBM”. It was a giant leap :) in the field of nanotechnology!  Now they’re working on measuring forces on an atomic scale.   Click on this link to the article, to find out more about it.  Atomic Scale Forces
