SPARK What is the half-life of hartium-90? 0 The mass of cobalt-60 in a sample is found to have decreased from 0.800 g to 0.200 g in a period of 10.5 years. From this information, calculate the half-life of cobalt-60. 0 If we start with a sample 1.000 g sample of hartium-90, 0.250 g will remain after 2.00 years. What is the half-life of hartium-90? How much hartium-90 will remain after 4.00 year? AGENDA 1) SPARK 2) SHARE OUT 3) LESSON 4) CLASS WORK 5) WRAP UP

FISSION AND FUSION 0 Nuclear fission = nucleus slammed with neutrons It will not happen spontaneously (which is why it is artificial transmutation). http://www.visionlearning.com/library/flash_viewer.php?oid=2391&mid=59 0 Nuclear fusion = combo of two nuclei into a larger atom. ***Fusion is the fusing of nuclei, makes heavier elements, requires high temperature, releases more energy than fission. 1) SPARK 2) SHARE OUT 3) LESSON 4) CLASS WORK 5) WRAP UP
