Answer 2

Explanation:

Electron gain enthalpy is sometimes also referred to as Electron affinity although there is a minute difference between them. Electron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom. During the addition of an electron, energy can either be released or absorbed.

Metals lose electrons to obtain the inert gas configuration. Hence, Sodium and Magnesium atoms will not add electrons easily. Some external energy is needed to add electron in their atoms. Hence, electron gain enthalpy for metals will be positive. Magnesium atom is small in size, so the attractive nuclear force will be more on the electrons whereas the size of Sodium atom is comparatively larger than Magnesium atom. Hence, the nuclear force applied on the electrons in the case of Sodium will be less.
