What is Electron Affinity?

Electron affinity refers to the amount of energy released when an electron is added to a neutral atom or molecule to form a negative ion. It is a measure of the tendency of an atom or molecule to capture an electron.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ \text{EA} = -200 - (-150) = -200 + 150 = -50 \]

The Electron Affinity is -50 kJ/mol.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ \text{EA} = -300 - (-250) = -300 + 250 = -50 \]

The Electron Affinity is -50 kJ/mol.
