Question

define electron gain enthalpy ​

Answer 1

It is the energy change that occurs when an electron is added to the outermost shell of a neutral gaseous atom.

Answer 2

Answer:

define electron gain enthalpy

• it is amount of energy required to add an electron in an out of motion or valence shell is known as electron gain enthalpy
• more electronegative element will gives more electron gain enthalpy
• as moving across the period electron gain enthalpy increases
• as moving down the group electron gain enthalpy decreases
