Overview
Electronegativity is a fundamental concept in chemistry that describes how strongly an atom can attract electrons in a bond. It plays a crucial role in determining the nature of chemical bonds, influencing whether they are ionic, polar covalent, or nonpolar covalent. Understanding electronegativity ...
Key Terms
Example: Fluorine has a high electronegativity, attracting electrons strongly.
Example: HCl is a polar bond due to the difference in electronegativity between H and Cl.
Example: O2 is a nonpolar bond as both oxygen atoms have the same electronegativity.
Example: Fluorine is rated 4.0 on the Pauling scale, the highest value.
Example: NaCl is formed by the ionic bond between sodium and chlorine.
Example: In H2O, oxygen and hydrogen share electrons to form covalent bonds.
