What is the basic difference between the terms electron gain enthalpy and electronegativity?

Explanation

To understand the basic difference between electron gain enthalpy and electronegativity, we can break it down into a step-by-step explanation:

### Step 1: Define Electron Gain Enthalpy
- **Electron Gain Enthalpy** is defined as the energy change that occurs when an isolated gaseous atom accepts an electron to form a negative ion. It reflects the tendency of an atom to gain an electron.

### Step 2: Define Electronegativity
- **Electronegativity**, on the other hand, is the ability of an atom in a chemical compound to attract shared electrons towards itself in a covalent bond. It indicates how strongly an atom can pull electrons when it is bonded to another atom.
