An element having low value of ionization energy and low value of electron affinity is likely to belong to
Correct answer: B. (b) Group IB.
- A. Group IA
- B. (b) Group IB.
- C. Group VIIA:
- D. Group VIII
Explanation
- **Correct Option: (b) Group IB** Explanation: Group IB elements typically have lower ionization energies and electron affinities compared to other groups, leading to easier loss of electrons and lower attraction for gaining electrons.- **Incorrect Options Explained:** (a) Group IA: Group IA elements have low ionization energies but high electron affinities, making them less likely to have low values for both ionization energy and electron affinity. (c) Group VIIA: These elements have high electron affinities and higher ionization energies compared to Group IB. (d) Group VIII: Elements in Group VIII (noble gases) have high ionization energies and zero or close to zero electron affinities, not low values for both.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
