Question- Which equation best describes the electron affinity of Cl? (and why?) Having a difficult time understanding the concept of electron affinity.
1) Cl(g) --> Cl+e' Delta E <0
2) Cl(g) --> Cl+ e' Delta E >0
3) Cl(g) + e' --> Cl (g) Delta E < 0
4) cl(g) + e' ---> Cl(g) Delta E >0
I am thankful to receive an expert help to solve the above problem
