how do you calculate the mass of an atom when given the exact masses of each fundamental particle?
add the masses of the proton and electron together
what is an isotope?
two atoms of the same element that have the same number of protons but a different number of neutrons
why do isotopes of the same element have the same chemical properties?
isotopes have the same electron configuration
chemical properties depend on the number of (outer) electrons
