What is the mass number of an atom with 5 protons and neutrons?
Boron has an atomic number of 5 which means it has 5 protons. We assume atoms are neutral so the atom also has 5 electrons. It has an atomic mass (average mass) of 10.811 which we would round up to 11 (the mass of the most common Boron atom) so it has 11 total particles in its nucleus (protons + neutrons).
