Questions: 1) What holds atoms together? an attraction of opposite charges 2) The atom is mostly empty space. Background Vocabulary Examine this picture. These are ISOTOPES of hydrogen. Discuss with a partner the similarities and differences between each isotope of hydrogen: Elements and Isotopes Videoclip #2 Questions 1) What is the atomic number? number of protons in the nucleus 2) 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-12 Carbon-13 Carbon-14 How Isotopes can be Useful… • Carbon-14 radiometric datingused to determine the age of fossils and living matter • Treatment of illnesses (i.e. cancer) Cobalt60 • CAT scans in medicine • Nuclear generators (nuclear fission) Nuclear fission • See desktop
