Linus Pauling who invented the Pauling scale assigned the electronegativity of fluorine as 4. There are many scales of it and one of them is the Pauling Scale. We calculate it rather than measuring it on a relative scale. HCL is an example of a polar covalent bond. That is more electronegative and it gives a small negative charge to the atom which helps in bonding. Moreover, this uneven sharing of electrons results in a small negative charge on the atom. Then the atom with higher-level takes the maximum share of the bonding electrons. When an atom is highly electronegative it is bonded covalently to an atom that that is lesser electronegative. When the atoms react with the similar electronegativity, they tend to form covalent bonds and in these bonds, and electrons share the atoms. Some examples of Ionic compounds are magnesium oxide, potassium fluoride, and lithium nitride. ![]() The compounds which form between the elements having a huge difference in the electronegativity are ionic compounds, and also have ionic bonding. The elements which are highly electropositive are capable of forming positive ions. It is the most electropositive element, followed by rubidium, potassium, and barium. Positive ionsĬesium comes at last when it comes to being electronegative. Atoms that have high electronegativity form negative ions. Negative Ionsįluorine is the most electronegative element after that comes, oxygen, chlorine, and nitrogen. ![]() It is directly proportional to the atom’s attraction for the electrons. Its symbol is a Greek letter that looks like an (X). 1.10 Solved Question for You ElectronegativityĮlectronegativity is a kind of measure that tells how strongly atoms attract the bonding electrons to them.
