Add your answer. If you were asked to describe metals and magnetism you could say that? A)all metals are attracted to magnets because they are able to create their own magnetic field. B)all metals are attracted by magnets; this is why we call metals ferromagnetic. C)only some metals are attracted to magnets because they do not have a magnetic field. D)only some metals are attracted by magnets;...
The mass of a single lead atom is 207.2 AMUs (atomic mass units) which when converted to grams weighs 3.440e-22 grams. Huzzah. The mass of a single lead atom is 207.2 AMUs (atomic mass units) which when converted to grams weighs 3.440e-22 grams. Huzzah.
Natural lead consists of four stable isotopes with mass numbers of 204, 206, 207, and 208, and traces of five short-lived radioisotopes. The high number of isotopes is consistent with lead's atomic number being even. Lead has a magic number of protons (82), for which the nuclear shell model accurately predicts an especially stable nucleus. Lead-208 has 126 neutrons, another magic number, which may explain why lead-208 is extraordinarily stable. With its high atomic number, lead is the heaviest element whose natural isotopes are regarded as stable; lead-208 is the heaviest stable nucleus. This title was formerly held by bismuth, with an atomic number of 83, until its only primordial isotope, bismuth-209, was found in 2003 to decay very slowly.
