the elements in group 18 or group 8 A or the noble gas group in the periodic table absorb the most energy.

Explanation:

The process of gaining energy or absorbing energy during gaining of electrons is the electron affinity property of the elements. As the behavior of elements having electron affinity is to release electron to attain stable state or to release excess energy. These elements will gain the most energy while gaining an electron. The most electron affinity elements present in the periodic table are in group 18 or group 8A. As the noble gases are elements with fully filled shells, they will attain the most energy on further addition of electron.

So the elements in group 18 or group 8 A or the noble gas group in the periodic table absorb the most energy.
