Why Electronegativity Decreases Across a Period in the Periodic Table Understanding electronegativity is essential for grasping how atoms interact in chemical bonding. One key trend in the periodic table is that electronegativity decreases as you move from left to right across a period. This pattern plays a vital role in predicting how atoms bond and how molecular polarity forms. In this article, we’ll explore why electronegativity decreases across a period, what factors influence this trend, and why it matters in chemistry. --- ### What Is Electronegativity?
