Why is electron affinity of Sn (Tin) more than Sb (Antimony)? This is given in JD Lee.
Answers
Its electronic configuration.Sn has 5s2 5p2.So it needs to be stable to become 5p3 but, in other hand Sb has 5s2 5p3 So, its stable than sn. so ea of sn is more.

Answer:
The answer to the given question is tin is a pure metal whereas antimony is a semi-metal.
The electron affinity of metal will always be greater than the electron affinity of nonmetal
Explanation:
The electron affinity is defined as the amount of energy released when a neutral atom in its gaseous state accepts an electron and it gets converted into a negatively charged ion.
It is caused by adding an electron to the gaseous atom.
Non-metals have a greater affinity than metals.
Tin (Sn), is a chemical element. It is a soft, silvery-white metal with a bluish tinge,
Antimony is a semi-metal. It is silvery, hard and brittle.
Based on the above reason, it is observed that tin is a pure metal and antimony is a semi-metal.
That is the reason for electron affinity of tin is more than the electron affinity of the antimony
