Question

Kylie kept 100 grams of radioactive bismuth in a container. She observed the amount of bismuth left in the container after regular intervals of time and recorded them in the table shown below. Based on the observations, which of these is most likely Kylie's inferenceTime (seconds) Amount of bismuth in container (in grams)

0 100
60.5 50
121.0 25
181.5 12.5

The half life period of radioactive bismuth is 121seconds.

The half life period of radioactive bismuth is 181.5 seconds.

The amount of bismuth left in the container after 242 seconds will be 6.25 grams.

The amount of bismuth left in the container after 242 seconds will be 10.25 grams.
