(a)

Interpretation Introduction

Interpretation:

The element that has a high electron affinity from Rb and Sr should be predicted.

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)
