Energy absorbed when an electron is added to an isolated atom in the gaseous state
 
Energy released when an electron is added to an isolated atom in the gaseous state
 
Energy required to take out an electron from an isolated gaseous atom
 
Power of an atom to attract an electron to itself
As we have learnt,
Electron affinity is the ability of any isolated gaseous atom to take up a free electron. Energy is released in the process of electron gain
