Thallium atomic radius
Web21 Nov 2024 · The atomic radius of Thallium atom is 145pm (covalent radius). It must be noted, atoms lack a well-defined outer boundary. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. WebFor example, the atomic-ionic radius of chlorine (Cl-) is larger than its atomic radius. The bond length between atoms A and B is the sum of the atomic radii, d AB = r A + r B. CrystalMaker uses Atomic-Ionic radii data from: Slater JC (1964) Journal of Chemical Physics 39:3199-Crystal Radii

A thallium atom has 81 electrons, arranged in the electron configuration [Xe]4f 5d 6s 6p ; 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 these involved in chemical bonding than it is for the heavier elements. Thus, very few electrons are available for metallic bonding, similar to the neighboring elements mercury and lead. Thallium, then, like its con…
