Boron has only two naturally occurring stable isotopes, boron-10 and boron-11. the average atomic mass of boron is 10.81 amu. which of borons two isotopes is more common?

Boron 11

Boron 11 is the most common isotope of boron, it represents 80% of boron found on the earth surface, it is a stable isotope metal, it occurs naturally and can also be synthesised by fission process.
