Why do members of the noble gas family have low boiling points ?

Text Solution

AI Generated Solution

### Step-by-Step Text Solution: 1. **Identify the Noble Gases**: The noble gas family consists of helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are located in Group 18 of the periodic table. 2. **Understand Their Atomic Structure**: Noble gases are monoatomic, meaning they exist as single atoms rather than molecules. This characteristic influences their physical properties, including boiling points. 3. **Examine Intermolecular Forces**: The primary forces acting between noble gas atoms are weak van der Waals forces, also known as dispersion forces. These forces arise due to temporary dipoles that occur when electron distribution around an atom fluctuates. ...
