Electron affinity variation in periodic table
WebThe electron affinity of inert gases is zero due to their stable electronic configuration. (c) He Ionisation energy decreases with an increase in the atomic size, so it decreases as one moves down a group. Then in that case, Ne, He and Ar are inert gases. He – Period 1, Ne – Period 2 and Ar – Period 3. 8.
