For these values, ages were calculated from Lead-210 activities using the constant rate of supply (CRS) model (Appleby and Oldfield 1983). The alta_lake_14C_ages object contains one uncalibrated Carbon-14 measurement from the Lead has an average atomic mass of 207.19u. The three major isotopes are: lead-206 (205.98u) lead-207 (206.98u) lead-208(207.98u) If isotopes lead-206 and lead-207 are present in the same percent abundace, what are the abundancies of each of the three major isotopes of lead?

lead in one direction; It can also result from abundant. The relative abundances of the four stable isotopes are approximately 1.5%, 24%, 22%, and 52.5%, combining to give a standard atomic weight (abundance-weighted average of the stable isotopes) of 207.2(1). Lead is the element with the heaviest stable isotope, 208 Pb. Chromate ions were added to a solution of PbCl 2 containing a known amount of 210 Pb, precipitating the lead as PbCrO 4. The precipitate contained 2030 “radioactive units”, and had a weight of 11.35 mg.
