Question

boron has 2 isotopes B11 and B12.if average atomic weight of boron is 11:2. find the percent abundance of each isotopes​

Answer 1

Answer:

Find relative % of each isotope. Hint: Isotopes are atoms of the same element with the same atomic number and different mass number. All isotopes of the same element have the same number of protons but different number of neutrons. Thus, the amount of B11=20% and B12=80% in the given isotope.
