In a naturally occurring sample, 19.8% of boron atoms have five neutrons and 80.2% have six neutrons. what is the mass number of each boron isotope? sketch a sample of 10 atoms that is nearly representative of a natural sample. what is the average mass of the atoms in your drawing? what is the atomic mass of boron? (boron-10 has a mass of 10.01294 amu and boron-11 has a mass of 11.00931 amu.)
