Question 9

why can less common isotopes be used as trackers?

Answer 9

they react the same way in a chemical reaction but can be detected from the most common isotope

Question 10

how can less common isotopes be tracked?

Answer 10

1. some are radioactive - scientists can measure and find the location/amount of radioactivity (carbon dating)
2. scientists can measure the differences in mass (determining global temp by using the ratio of oxygen-18:oxygen-16
