Which of the following has the highest positive electron gain enthalpy?1)F 2)O- 3)Na+ 4)Mg2+ Which of the following has the highest positive electron gain enthalpy?1)F 2)O- 3)Na+ 4)Mg2+
Electron gain enthalpy is the energy released during the addition of one mole of electron to the gaseous atom or element or ion. As F is neutral small amount of energy is released during the addition. As Na+ and Mg2+ are in need of electron as they are positively charged species they take up electron quickly. But O is already having negative charge here, due to electron electron repulsion, this addition releases more energy
