Answer:

The atomic mass of boron in the periodic table is the weighted average of the atomic masses of its isotopes. This means that the atomic mass takes into account the relative abundance of each isotope.

Calculating Atomic Mass of Boron:


  • 10B has a relative abundance of 19%

  • 11B has a relative abundance of 81%


To calculate the atomic mass of boron, we use the following formula:

atomic mass = (mass of isotope 1 × relative abundance of isotope 1) + (mass of isotope 2 × relative abundance of isotope 2)

Plugging in the values for boron, we get:

atomic mass = (10 × 0.19) + (11 × 0.81) = 10.81

Therefore, the atomic mass that should appear for boron in the periodic table is 10.8.
