Answer 1

Answer:

Energy change associated with the gaining of an electron by the atom in the gaseous state.

Explanation:

What is electron affinity?

• energy change associated with the gaining of several electrons required to complete the outermost orbital of the atom in the gaseous state. FALSE. Electron affinity is associated with the gain of only 1 electron.
• energy change associated with the gaining of a proton by the atom in the gaseous state. FALSE. Protons cannot be gained nor lost.
• energy change associated with the gaining of an electron by the atom in the gaseous state. TRUE. This is the definition of electron affinity.
• energy change associated with the gaining of several electrons to complete the outermost sublevel of the atom in the gaseous state. FALSE. Electron affinity is associated with the gain of only 1 electron.
