sort each isotope based on the abundance of isotopes on earth, as shown in the phet simulation by selecting nature's mix, and on planet x given the following information: average atomic mass values for planet x (amu) oxygen 16.09 chlorine 36.97 boron 10.31 although there are three isotopes for oxygen, you only need to sort the two listed.
drag the appropriate items to their respective bins.
1. o-16
2. o-18
3. cl-37
4. b-11
5. cl-35
6. b-10
choices (bins of categorization which 1-6 must be separated into)
a. more abundant on earth
b. more abundant on planet x
c. approximately equal abundance on both.
