Show that the neutron number for the following nuclides generally exceeds the atomic number for nuclei with atomic numbers greater than 20: tin-126, phosphorus-30, bromine-80, carbon-12, krypton-84, and sulfur-32. (Enter your answer in the form AZX_{N}. Separate substances in a list with a comma.)

Sulfur has four naturally occurring stable isotopes. The onewith the lowest mass number is sulfur-32, which is also the mostabundant (95.02%).a) What percentage of the S atoms in a matchhead are ³²S?(b) The isotopic mass of ³²S is 31.972070 amu. Is the atomicmass of S larger, smaller, or equal to this mass? Explain.
