8. Which of the following atoms has the largest magnitude electron affinity?
(a) Sodium (Na)
(b) Rubidium (Rb)
(c) Caesium (Cs)
(d) Potassium (K) (
e) Lithium (Li)
Ans : e) Lithium (Li)
The electron affinity of the elements decrease down the group in a modern periodic table due to increase in the atomic radius of the elements.
The element lying at the top if accepts the electron , it will be closer to the nucleus and hence face more attraction . So here the largest magnitude of electron affinity is of lithium.
