Mass of lead atom
A lead atom has 82 electrons, arranged in an electron configuration of [Xe]4f 5d 6s 6p . The sum of lead's first and second ionization energies—the total energy required to remove the two 6p electrons—is close to that of tin, lead's upper neighbor in the carbon group. This is unusual; ionization energies generally fall going down a group, as an element's outer electrons become more distant fro… WebThe atomic weight of helium is 4.002602, the average that reflects the typical ratio of natural abundances of its isotopes. Atomic weight is measured in atomic mass units (amu), also called daltons. See below for a list of chemical elements and their atomic weights.
