  1. Atom Structure and Isotopes Mrs. Gonzales MFMS

  2. Review: Atom Structure http://www.schooltube.com/video/6e90652c7acd499ba85d/Just%20how%20small%20is%20an%20atom?

  3. Questions: 1) What holds atoms together? an attraction of opposite charges 2) The atom is mostly empty space.

  4. Background Vocabulary Examine this picture. These are ISOTOPES of hydrogen. Discuss with a partner the similarities and differences between each isotope of hydrogen:

  5. Elements and Isotopes

  6. Videoclip #2 Questions • What is the atomic number? number of protons in the nucleus • What are isotopes? Atoms with the same number of protons, but a DIFFERENT number of neutrons. 3) How many protons and neutrons are in the following carbon isotopes? Carbon-12Carbon-13Carbon-14

  7. How Isotopes can be Useful… • Carbon-14 radiometric dating- used to determine the age of fossils and living matter • Treatment of illnesses (i.e. cancer) Cobalt-60 • CAT scans in medicine • Nuclear generators (nuclear fission)
