Interpretation : The more abundant isotope of boronis to be identified.
Concept Introduction : The weighted average mass of the atoms in a naturally occurring sample of an element is the
Answer to Problem 22SP
Boron-11 is the most abundant isotope of boron.
Explanation of Solution
Given information:
The isotopes of boron are boron-10 and boron-11.
The atomic mass of boron is 10.81 amu.
The weighted average mass of the atoms in a naturally occurring sample of an element is the atomic mass.
Compare the atomic mass to the mass of each isotope.
Find the mass of the isotope whole value is closer to atomic mass.
Among the given isotopes, the mass of boron-11 is closer to atomic mass.
So, boron-11 is the most abundant isotope than boron-10.
