The various factors which influence the electron affinity can be explained under following heads:-
1. NUCLEAR CHARGE
Greater the nuclear charge, greater will be the attraction for the incoming electron and as a result larger will be the value of electron affinity.
2. ATOMIC SIZE
Larger the size of an atom, larger will be the distance between the nucleus and the incoming electron. Thus, smaller will be force of attraction felt by incoming electron and hence smaller will be the value of Electron affinity.
3. ELECTRONIC CONFIGURATION
Stable the configuration of an atom, lesser will be its tendency to accept an electron and hence lower the value of its electron affinity.

the electron affinity of an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.
The factors affecting electron affinity are
1)NUCLEAR CHARGE. Greater the nuclear charge, greater will be the attraction for the incoming electron and as a result larger will be the valueof electron affinity.
2) ATOMIC SIZE. Larger the size of an atom, larger will be the distance between the nucleus and the incoming electron. ...
3) ELECTRONIC CONFIGURATION.
