Isotopes

We extended our learning about neutrons yesterday with a lesson about isotopes.  The Lesson 13 PowerPoint explains how certain elements like carbon always contain the same number of protons, but may contain different numbers of neutrons.  Students then practiced calculating the number of protons, neutrons, and electrons on the Lesson 13 Worksheet.
