Introduction
• The electron gain enthalpy decreases down the group. • Because of the compact nature of oxygen atom, it has less negative electron gain enthalpy than sulphur. • However, from sulphur onwards the value again becomes less negative up to polonium.
Pre-Requisites:
Periodic table, elements, electron gain enthalpy
Activity:
Eggs contain sulfur.
Real Life Question:
What elements are present in eggs?
