Higher value of electron affinity means__________________?
Correct answer: B. Atom will gain electron easily
- A. Atom will lose electron easily
- B. Atom will gain electron easily
- C. Atom may form di-positive ion
- D. The reason is unknown
Explanation
A higher electron affinity means that an atom releases more energy when it accepts an electron, so it has a greater tendency to gain an electron. The likely mistake is choosing loss of an electron, which is related to low ionization energy rather than high electron affinity.

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.
