Chem. Soc., 1914, cv., 1402) I gave an account in NATURE, It was found that all of the radioactive specimens possess a lower atomic weight than ordinary lead, as determined under identical conditions, the deficiency in one case amounting to as much as 0.75 of a unit.
Lead weighs 11.342 gram per cubic centimeter or 11 342 kilogram per cubic meter, i.e. density of lead is equal to 11 342 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure. In Imperial or US customary measurement system, the density is equal to 708.05793 pound per cubic foot [lb/ft³], or 6.55609 ounce per cubic inch [oz/inch³] .

Find the following: To calculate atom weight by method two, we need to look at the Periodic Table of the Elements. There we see gold, chemical symbol Au, as element number 79. At the bottom of the little square, we see the number 196.97. This is the atomic weight of gold. The atomic weight in grams of an element equals the weight of an Avogadro’s number of that Atomic Number = 84 Atomic Weight = 209 Reference E95 : Isotope : Mass : Abundance : Spin : Mag Moment : 210 Po: 209.982848: Trace: 0 : 211 Po: 210.986627: Trace: 9/2 : 216 Po: 216.001889: Trace: 0 : 218 Po: 218.0089: Trace: 0 : Po I Ground State 1s 2 2s 2 2p 6 3s 2 3p 6 3d 1 0 4s 2 4p 6 4d 1 0 4f 1 4 5s 2 5p 6 5d 1 0 6s 2 6p 4 3 P 2 Lead's close-packed face-centered cubic structure and high atomic weight result in a density of 11.34 g/cm 3, which is greater than that of common metals such as iron (7.87 g/cm 3), copper (8.93 g/cm 3), and zinc (7.14 g/cm 3).
