This video unpacks the concept of electron gain enthalpy in depth—clearly explaining what it means for an element to have a positive or negative electron gain enthalpy, and why this difference is chemically significant. We will explore how different factors affect electron gain enthalpy like atomic size, effective nuclear charge, screening effect and the effect of half-filled and fully-filled subshells. Along the way, we will also analyze how electron gain enthalpy generally changes across a period and down a group, and more importantly, examine the notable exceptions.
