Electronegativity
Electronegativity, a fundamental concept in chemistry, characterizes the ability of an atom to attract electrons within a chemical bond. It plays a crucial role in understanding the behavior of elements in various chemical reactions and molecular structures. First proposed by Linus Pauling in 1932, electronegativity values help predict bond polarity, molecular shapes, and reactivity patterns. This property influences diverse phenomena, from the solubility of substances to the nature of chemical bonds in compounds. Understanding electronegativity is essential for comprehending the principles governing molecular interactions and the properties of matter in the realm of chemistry.
