Increasing electronegativity for the following chemical would be: Florine > Carbon > Boron > Aluminum > Calsium > Cesium > Barium.
When atoms can attract electrons during chemical bonding, they are said to be electronegativity.
Electronegativity rises from left to right across the periodic table. The reason for this is that as the atomic number rises, there are more protons. Due to the growing size of the atoms, electronegativity decreases from top to bottom. As a result, fluorine is regarded as the element with the highest electronegative potential, whereas cesium has the lowest. The electronegativity of a halogen is thought to be high, while that of an alkali metal or an alkaline earth metal is thought to be low.
