The atomic mass of lead (Pb) is approximately 207.2 atomic mass units.
The element with an atomic mass of 207.20 is lead (Pb).
relative atomic mass
In period 6, the two elements that have the same relative atomic mass are lead (Pb) and thallium (Tl), both of which have an atomic mass of approximately 204.37 u. Their similar atomic masses can lead to some confusion, but they are distinct elements with different properties and uses in chemistry and industry.
Lead's atomic mass is 207.2 Its atomic number is 82
The atomic mass of lead (Pb) is approximately 207.2 atomic mass units.
The element with an atomic mass of 207.20 is lead (Pb).
The relative formula mass of lead oxide (PbO) is calculated by adding the atomic masses of the elements in the formula. The atomic mass of lead (Pb) is 207.2 g/mol, and the atomic mass of oxygen (O) is 16.0 g/mol. Therefore, the relative formula mass of lead oxide is 207.2 + 16.0 = 223.2 g/mol.
The atomic number of lead, Pb, is 82. Its atomic mass depends on the isotope, as the number of electrons can vary. Its atomic weight (average relative mass ) on the periodic table is 207.2.
