Definition
Electron shielding is the phenomenon where inner electrons in an atom reduce the effective nuclear charge felt by outer electrons, making them less tightly bound to the nucleus.
Summary
Electron shielding is a fundamental concept in chemistry that explains how inner electrons affect the behavior of outer electrons in an atom. This phenomenon is crucial for understanding various chemical properties, such as ionization energy and atomic size. As inner electrons repel outer electrons, they reduce the effective nuclear charge that outer electrons experience, making them easier to remove and influencing how atoms bond with one another. Understanding electron shielding helps students grasp the trends observed in the periodic table and the reactivity of different elements. By learning about effective nuclear charge and the role of valence electrons, students can better predict how atoms will interact in chemical reactions, making this concept essential for further studies in chemistry and related fields.
