Cesium is a group one metal which has a large atomic radius. This means that the outer shell of electrons is a great distance away from the pull of the nucleus which causes a decrease in the affect of the nuclear charge. There are many electron shells in between which causes shielding. This would reduce the atom's ability to pull electrons in a bond making it less electronegative. Group one elements would rather lose their outer shell electron to become stable than gain another electron.

What element conducts electricity and also melts below 100 degree celsius?
There are at least three metals that qualify: mercury, gallium, and cesium.
What is the least reactive element in the group 2 of the periodic table of elements?
The Zinc Family also known as group IIB is the second least reactive I believe. The least reactive family is the one with a full p sublevel, the noble gases, the next least reactive would be the family with a full d sublevel. Since group IIB has a full d sublevel, it must be the next least reactive family.
What is the least common element in the atmosphere of the earth?
Nitrogen is the least abundant element in the atmosphere of the Earth. The most abundant element in the atmosphere of the Earth is oxygen.
Where is cesium found today?
The richest source of caesium in nature, at least in 1985, was a deposit of pollucite, a mineral that is hydrated mixed silica of aluminum and caesium, near Bernic Lake, Manitoba, Canada. The primary uses of the element are in photoelectric cells, as a hydrogenation catalyst, in atomic clocks, and in ionic propulsion systems for space vehicles.
Is hydrogen more electronegative than chlorine?
No, on the Arbitrary Pauling Scale hydrogen's relative electronegativity is less than that of chlorine, indicating that hydrogen attracts electrons in a bond more strongly. In hydrogen chloride (hydrochloric acid as an acid) the two shared electrons would be pulled towards hydrogen in a polar covalent bond. F, Cl, N, and O are the four most electronegative elements. Metals are least electronegative and nonmetals are the most.
Which element is given first the more electronegative or less electronegative?
fluorine is most electronegative and cesium is least electronegative
What element is the least electronegative on the periodic table?
Cesium, Cs
What element is least electronegitive?
Francium is the least electronegative element
Which element has the lowest electronegativity value?
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 (
What is the least electronegative element in the third period?
It is sodium metal.
What is the least electronegative element?
Francium. At 0.7 electronegativity.
What is oxide an element or a compound?
An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.
Is oxide an element or an compound?
An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.
What makes the most stable atom?
Probably cesium fluoride, since it combines the least electronegative (non-radioactive) element with the most electronegative one.
What is the least reactive element in group6?
Group seven is known as the halogen group. The least reactive element in group seven is astatine. Fluorine is the most reactive.
What is oxygen's favorite element?
I don't understand what "favorite" is supposed to mean in this context. Oxygen is highly electronegative and will preferentially combine with the least electronegative element available, but that's not really a matter of "favorite", it's a matter of energetics.
Which element when combined with chlorine would most likely fom an ionic compound?
Among the naturally occurring elements, the most likely one would be cesium, the least electronegative of all elements. In practice, any of the other alkali metals and any of the alkaline earth metals would usually react readily with chlorine gas, as would many of the transition metals.
