Relative atomic mass of thallium

WebNov 26, 2024 · Atomic Mass of Thallium. Atomic mass of Thallium is 204.3833 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams. WebThe relative atomic mass of thallium is 204.383, the atomic number is 81, and the electron configuration is (Xe) 4f14 5d10 6s2 6p.
