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 (

Do lithium has the lowest electronegativity?
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.
What element has the lowest electronegativity bromine lithium carbon fluorine?
Lithium has the lowest electronegativity, then carbon, bromine and fluorine has the highest electronegativity of any atom.
Which element in period 4 has the highest electronegativity?
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).
What is the element with the highest electronegativity value called?
This chemical element is francium (Fr).
Which element has a higher electronegativity value Rubidium or Iodine?
Iodine

What element has the lowest electronegativity value a cesium b helium calcium d fluorine?
CESIUM :)
What element has the lowest electronegativity bromine lithium carbon fluorine?
Lithium has the lowest electronegativity, then carbon, bromine and fluorine has the highest electronegativity of any atom.
Where are the atoms with the lowest electronegativity value located?
Atoms with the lowest electronegativity values located on the leftmost part of the Periodic Table. The atom with the lowest electronegativity belongs to Francium.
Which element in period 4 has the highest electronegativity?
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).
What element has the lowest electronegativity barium calcium magnesium strontium?
Barium.
Which element has the smallest electronegativity in period 6?
Caesium, at 0.79 on the Pauling scale, has the lowest electronegativity. However, the electronegativity of many elements in period 6 is not established.
What is the element with the highest electronegativity value called?
This chemical element is francium (Fr).
Which element has a higher electronegativity value Rubidium or Iodine?
Iodine
Why element is the most reactive?
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.
What is the most likely electronegativity value for a metallic element?
The question is too general; iron for example has a Pauling electronegativity of 1,83.
Is it true that elements with a high electronegativity value tend to form positive ions?
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.
