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.

1. O-16 : More abundant on planet X
2. O-18 : More abundant on Earth
3. Cl-37 : More abundant on planet X
4. B-11 : : More abundant on Earth
5. Cl-35 : More abundant on Earth
6. B- 10 : More abundant on planet X
Explanation:
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
1. O-16 : More abundant on planet X
Average atomic mass of oxygen = 16.09 amu
As, the average atomic mass of oxygen is closer to the mass of O-16 isotope. This means that the relative abundance of O-16 isotope is the higher as compared to the other isotopes on planet X.
2. O-18 : More abundant on Earth
3. Cl-37 : More abundant on planet X
Average atomic mass of chlorine = 36.97 amu
As, the average atomic mass of chlorine is closer to the mass of Cl-37 isotope. This means that the relative abundance of Cl-37 isotope is the higher as compared to the other isotopes on planet X.
4. B-11 : More abundant on Earth
Average atomic mass of boron = 10.31 amu
As, the average atomic mass of boron is closer to the mass of B-10 isotope. This means that the relative abundance of B-10 isotope is the higher as compared to the other isotopes on planet X.
5. Cl-35 : More abundant on Earth
6. B- 10 : More abundant on planet X
