Radioactive Lab

Aim: What is a one- fractional bread and butter? What is the several(prenominal) young find or baring using one-half(a)(prenominal) life? Procedures: 1.) There are 5 bags in the room. 2.) You and your classify testament start at your assigned fossil; you cook a certain amount of time at from each one commit. 3.) In the end you grass go back to a station if you must 4.) At your table open up the bag, one food colour puff is the isotope while the otherwise colored puff is the putrefy product. 5.) Count the two and forecast the half life, record your calculations in the Report mainsheet. 6.) Complete the lab questions when finished. Data: Report Sheet fossil NumberNumber of Parent IsotopesNumber of chime in down ProductsNumber of Half LivesAge of Fossil 1154521,408 million eld 253532,112 million days 330100.52.25 trillion days 4252514.5 jillion years 54551/52.8 zillion years Formulas: work out the number of half lives of the agent exam pled and you get in the epoch of the fossil Questions: 1.) The fossils from oldest to youngest are 4, 5,2,1,3. 2.) 3 and 2 were very closing curtain in age. 3.) Fossil #4 came from the time just after(prenominal) the realiseation of the earth because Fossil #4 existed 4.5 billion years ago and the Earth originated 6 billion years ago. 5.

) Yes, scientists can use more than one event of isotope to employment the comparable rock or fossil because any(prenominal) can form around the same time and some cant. 6.) I would use Uranium 235 to date a sample that was estimated to be about 1 million years old. I would use Uranium 235 because Uranium is us! ed to date back fossils from millions of years ago and because uraniums half life is proximate to 1 million than Thorium 232. culture: A half life is the time required for half of the unstable isotope to pitch into a stable decay product. The about recent discovery using half life is old-fashioned Bones tack together in Wisconsin. The bones make been dated to between 5,600 and 5,800 years old using half life. They were discovered in unsanded Hope Cave at Cherney Maribel Caves County Park in...If you want to get a full essay, arrange it on our website: OrderCustomPaper.com
