Electron affinity of an atom is the energy released when an electron _to an empty or partially filled orbital of an atom to form_?
Correct answer: C. Added, anion
- A. Removed,cation
- B. Added,cation
- C. Added, anion
- D. Removed, anion
Explanation
c) Added, anion: This is the correct option. Electron affinity is the energy released when an electron is added to an atom to form an anion. Anions are negatively charged ions that have gained one or more electrons.

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.
