$\huge\underline\red{Answer}$

Electron affinity :-

• Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons

Example :- Li < Be < B < C < N < O < F
