Caesium, at 0.79 on the Pauling scale, has the lowest electronegativity. However, the electronegativity of many elements in period 6 is not established.
period 6
The element that has 86 protons in period 6 is Radon (Rn).
There is no element in period 3 group 6. The element at period 3, group 16 (called on very old periodic tables group VIA) is sulfur (S).
Electronegativity increases as you go from the bottom left corner of the periodic table to the upper right corner. The element with the lowest electronegativity is thus francium (Fr). However, this element is radioactive, and so generally the least electronegative element that you can really use is cesium (Cs). Generally speaking, this whole first column (the alkali metals) all have very low electronegativities, but the lower down the column, the lower the electronegativity.(Francium may not be the least electronegative element due to the relativistic effects, which is evident from its ionization energy (> Cs) and standard electrode potential (
Caesium is a Period 6 element.
The element in the sixth period in column 13 is tellurium, with symbol Tl.
The element Radon (atomic symbol Rn) is the noble gas found in Period 6 of the periodic table.
Chromium is the element in period 4 and group 6.
This chemical element is astatine (At).
The element with 75 protons in period 6 is Rhenium (Re), which has an atomic number of 75.
There are 6 elements. vanadium is a example one.
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
