Definition
Electronegativity measures an atom's ability to attract shared electrons in a molecule. It influences bond polarity and chemical reactions. Electronegativity trends across periods and groups provide insights into the nature of chemical bonds and the behavior of compounds.
Summary
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 helps predict molecular behavior and properties, making it essential for studying chemical reactions and compound formation. The periodic trends of electronegativity reveal that elements on the right side of the periodic table, such as fluorine and oxygen, have higher electronegativities compared to those on the left, like sodium and potassium. This knowledge is vital for applications in various fields, including pharmaceuticals and materials science, where the behavior of molecules is critical for innovation and development.
