A thallium atom has 81 electrons, arranged in the electron configuration [Xe]4f145d106s26p1; of these, the three outermost electrons in the sixth shell are valence electrons. Due to the inert pair effect, the 6s electron pair is relativistically stabilised and it is more difficult to get t...

Crystallographic analysis reveals that the thallium in this case is slightly displaced away from the ring centroid toward the unique ring carbon located between the borons, which is the site of highest electron density. The displacement, however, is less than that observed in the companion ...
It is the only element to form a stable singly charged cation with the outer electron configuration (n-1)d10ns2, which is, unusually enough, not an inert gas configuration. In water the colourless, more stable thallous ion, Tl+, resembles the heavier alkali metal ions and silver; the ...
