dense enough to prevent massive cores from further collapse. As this occurs thegravitational pressureis so intense that the negatively-charged electrons and positively-chargedprotonsthat comprise the iron nuclei in this stellar core are crushed together, creating a sea of uncharged, or neutralneutrons...
of the mass of a single carbon-12 atom, at rest. The protons and neutrons of the nucleus account for nearly all of the total mass of atoms, with electrons and nuclear binding energy making minor contributions. Thus, the numeric value of the atomic mass w...
