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 (
Generally speaking, metals have low electronegativity. The element with the lowest is cesium.
That element is cesium (Cs, #55). Its electronegativity is so low because cesium only has 1 valence electron and it's a long way (6 energy levels) away from the nucleus.
Cesium (or caesium) has the lowest electronegativity.
Francium is more electronegative (Cs=0,79, Fr=0,70).
The element the has the lowest electronegativity is Francium. It has an electronegativity of 0.7 on the Pauling scale. The element with the highest electronegativity is Fluorine.
Helium
francium
No. the element francium will have the lowest electronegativity. However it is radioactive and for practical purpose, cesium is considered to be the element with lowest electronegativity.
Lithium has the lowest electronegativity, then carbon, bromine and fluorine has the highest electronegativity of any atom.
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
This chemical element is francium (Fr).
Iodine
No. the element francium will have the lowest electronegativity. However it is radioactive and for practical purpose, cesium is considered to be the element with lowest electronegativity.
CESIUM :)
Lithium has the lowest electronegativity, then carbon, bromine and fluorine has the highest electronegativity of any atom.
Atoms with the lowest electronegativity values located on the leftmost part of the Periodic Table. The atom with the lowest electronegativity belongs to Francium.
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
Barium.
Caesium, at 0.79 on the Pauling scale, has the lowest electronegativity. However, the electronegativity of many elements in period 6 is not established.
This chemical element is francium (Fr).
Iodine
This rare metal has the lowest electronegativity on the periodic table. With an electronegativity number of 0.7 this element donates it's electron very easily to the higher electronegative nonmetals.
The question is too general; iron for example has a Pauling electronegativity of 1,83.
The electronegativity value tells you how much that element "wants" an electron, therefore, an element with a high electronegitivity value would generally give a negative ion. The definition of a negative ion is an atom with more electrons than protons.
