Electron affinity is the energy released when an electron is added to the gaseous atom or ion.
Electron affinity increases by moving from left to right in periodic table and decreases by moving from up to down.
So the correct answer is Te
Xe: being as noble gas it is unacceptable to gain an electron
The values of electron affinity for these elements:
Ba (13.9 kJ/mol) - Te (190.1 kJ/mol) - Xe (-80 kJ/mol) - Cs (45.5 kJ/mol)
