Welllllll,
I was sick today and switched the plan. If you were in class you should do the following worksheet HERE using a computer simulation. If you weren't there do THIS instead. Either way you should be able to calculate the number of protons, neutrons and electrons in different atoms and ions. Make sure you can write the standard symbol to show different isotopes.
Quick safety quiz on Monday, we will look at the practice quiz first and have some time to review.
