Mass numbers are used to identify different isotopes of an element and are a count of the protons and neutrons found in that isotope's nucleus. Interestingly, the number of protons will remain constant, regardless of the isotope, but the number of neutrons will change. This is because an ato...
The atomic mass of boron is 10.81. Note that this is the value listed in theperiodic tablefor the atomic mass of boron.Although the atomic numberof boron is 10, its atomic mass is nearer to 11 than to 10, reflecting the fact that the heavier isotope is more abundant than the lighter i...

we know that isotopes are atoms with the same atomic number but different mass numbers due to a different number of neutrons. the mass number of an element is a whole number whereas the actual mass of an atom is not a whole number except for carbon-12. for example, the atomic mass of...
