Electron affinity of an atom is the energy released when an electron __________to an empty or partially filled orbital of an atom to form_________?
- A
Removed,cation
- B
Added,cation
- C
Added, anion
- D
Removed, anion
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.
a) Removed, cation: This option means that electron affinity is the energy released when an electron is removed from an atom, resulting in the formation of a cation. Cations are positively charged ions that have lost one or more electrons.
b) Added, cation: This option is incorrect. Electron affinity is not the energy released when an electron is added to an atom to form a cation. Rather, it is the energy released when an electron is added to an atom to form an anion.
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.
d) Removed, anion: This option is incorrect. Electron affinity is not the energy released when an electron is removed from an atom to form an anion. The correct process is the addition of an electron to an atom to form an anion.
