(a)
Interpretation:
An element with greatest
Concept introduction:
Electron affinity:
In a gaseous state isolated neutral atom, energy released when an electron is introduced in outermost shell is known as electron affinity. Greater the negative value of electron affinity, the atom has more tendency to accept an electron.
(b)
Interpretation:
An ion with largest ionic radii in the given set has to be identified and explained.
Concept introduction:
Ionic radii:
It is the half of the distance between two ions which are close together. The size of ions depends on charges of the ions. Ions with positive charge called cations are smaller in size than negative charged anions.
