C. Why is it difficult to accurately predict lead ’s most common isotope? 7. Other articles where Lead-206 is discussed: dating: Model ages: For example, the ratio of lead of mass 206 relative to that of mass 204 has changed from an initial value of about 10 present when Earth was formed to an average value of about 19 in rocks at the terrestrial surface today. This is true because uranium is continuously… A. Based on the average atomic mass of lead, which isotope do you think is the most common? Explain your reasoning: B.

Molecular weight calculation: 207.2 + 15.9994 Locate atomic mass on the periodic table. Most standard periodic tables list the relative atomic masses (atomic weights) of each element. This is almost always written as a number at the bottom of the element's square on the table, under its one or two letter chemical symbol. 7 rows 20 rows Lead (Pb) Atomic Data for Lead (Pb) Atomic Number = 82 Atomic Weight = 207.2 Reference E95 Element Lead (Pb), Group 14, Atomic Number 82, p-block, Mass 207.2.
