P7-Analyzing the M and M Lab Data

What do the M and M candies in the lab represent?

• Option 1: Atoms of elements

• Option 2: Atoms of stable isotopes

• Option 3: Atoms of radioactive isotopes

• Any of the 3 options is correct

What does '100' represent?

• Option 1: The starting # of radioactive isotopes

• Option 2: The original amount of radioactive isotopes

• Option 3: The initial mass of radioactive isotopes

• Any of the 3 options is correct

What do the group names represent?

• Option 1: Same types of radioactive isotopes

• Option 2: Different types of radioactive isotopes

Which over-all trend BEST describes the remaining # of M and M's from shake #1 through 10?

• As the shake # increases, the remaining # of M and M's decreases.

• As the shake # decreases, the remaining # of M and M's increases.

• As the shake # increases, the remaining # of M and M's fluctuates.

• As the shake # decreases, the remaining # of M and M's stays constant.

Which over-all trend BEST describes the decayed M and M's from shake #1 through 10?

• As the shake # increases, the decayed M and M's decreases.

• As the shake # decreases,the decayed M and M's and M's increases.

• As the shake # increases, the decayed M and M's decreases and then fluctuates.

• As the shake # decreases, the remaining # of M and M's stays constant.

Which over-all trend BEST describes the total # of decayed M and M's from shake #1 through 10?

• As the shake # increases, the total # of decayed M and M's decreases.

• As the shake # decreases, the total # of decayed M and M's increases.

• As the shake # increases, the total # of decayed M and M's decreases and then fluctuates.

• As the shake # decreases, the total # of decayed M and M's stays constant.

Based on the P7-Group Data, which is the SHORTEST half-life that the M and M's undergo before it finally decayed into a stable isotope?

• less than 5 half-lives

• 5 half-lives

• 10 half-lives

• more than 10 half-lives

Based on the P7-Group Data, which is the LONGEST half-life that the M and M's undergo before it finally decayed into a stable isotope?

• less than 5 half-lives

• 5 half-lives

• 10 half-lives

• more than 10 half-lives
