Concept Introduction:
The amount of energy required to add an electron to the atom to form negative ion is known as electron affinity. The factors affecting electron affinity are shown below:
- It is inversely proportional to the size of an atom.
- It is directly proportional to the effective nuclear charge.
- It is inversely proportional to the stable electronic configuration.
(b)
Interpretation:
The element that has a high electron affinity from Pm and F should be predicted.
