Document Summary
Human development midterm review: beryllium has an atomic number of 4 and an atomic mass of 9. How many neutrons? (subtract atomic number from atomic mass) 5 neutrons (9-4 = 5: isotopes of an element differ due to the number of, protons, neutrons, electron, both protons and electrons, neutrinos, carbon dating is a common method employed in dating certain kinds of fossils. It is based upon he radioactive decay of an isotope of carbon (c14). Atomic is 6 so subtract 6 from 14 and you get 8. Releases an electron from the nucleus (called betaradiation) (beta release) Carbon 14 has 8 neutrons and 6 protons. One of the neutrons breaks up inside the nucleus and it becomes a proton + electron (called betaradiation) Nitrogen has a total of 7 protons now: how can radioisotopes be used to detect thyroid tumours, list and describe 4 kinds of bonds that are found between atoms.
