Question

1. boron has two naturally occurring isotopes boron - 10 and boron - 11. which isotope is more abundant on earth? use grammatically correct sentences to explain how your group determined the answer.

Explanation:

Boron - 11 is more abundant on Earth. This is determined by looking at the average atomic mass of boron which is approximately 10.81. Since it is closer to 11, boron - 11 must be more abundant as the average atomic mass is a weighted - average of the masses of its isotopes based on their relative abundances.

Answer:

Boron - 11 is more abundant on Earth.
