  6. Half Life and Time • Half-Life: The amount of time it takes for a particle to lose __________ its mass

  7. Half Life and Time The half-life for gold-198 is about 3 days. If it has been 6 days how many half-lives has the gold gone through?

  8. Half Life and Time Neon-10 went through two half-lives in 40 seconds. How long does it take to go through one half-life?

  9. Half Life in Fractions • To represent half-life in fractions, every time a substance goes through a half-life multiply the amount of substance by a _________.

  10. Half Life in Fractions If Thorium-232 undergoes 1 half-life then what fraction of the particles would be left?

  11. Half Life in Fractions If there is 1/8 of Strontium-90 left, then how many half-lives has it been through?

  12. Finding the Mass of an Object • If you are trying to find the remaining amount of a substance, multiply the amount by the __________ left.

  13. Finding the Mass of an Object If I 10g of Bismuth-208 goes through 1 half-life, then how much is left?

  14. Finding the Mass of an Object If I 20g of iodine-131 goes through 2 half-lives, then how much is left?

  15. Half Life in Graphs • Every half-life decreases the amount of mass in ___________.

  16. Draw graphical representation of a substance that goes through 4 half lives. Amount of Mass Number of Half Lives

  17. Guided Practice SHOW and TELL

  18. TIME The half-life for Radon is about 3 days. If it has been 6 days how many half-lives has the gold gone through?

  19. TIME The half-life for Carbon-10 is about 20 seconds. If it has been 60 seconds how many half-lives has the carbon gone through?

  20. TIME Boron went through 2 half life and it took 6 days. How long is one half life?

  21. TIME C-10 went through 3 half-lives in 60 seconds. How long is the half-life for C-10?

  22. FRACTIONS If Silver-111 went through 2 half lives then what fraction would be remaining?

  23. FRACTIONS If Pb-210 went through 4 half lives then what fraction would be remaining?

  24. FRACTIONS If 1/8 of Gallium-72 is left, then how many half lives has it been through?

  25. FRACTIONS If 1/16 of Sulfur-35 is left, then how many half lives has it been through?

  26. FINDING THE MASS If I 10g of oxygen-19 goes through 1 half-life, then how much is left?

  27. FINDING THE MASS If I 200g of sulfur-37 goes through 2 half-lives, then how much is left?

  28. FINDING THE MASS If I 20g of Chlorine-39 goes through 3 half-lives, then how much is left?

  29. FINDING THE MASS If I 32g of iodine-130 goes through 4 half-lives, then how much is left?
