What is the nature of the forces present in the noble gas atoms ?

Answer

To answer the question regarding the nature of the forces present in noble gas atoms, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify Noble Gases**:
- Noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These gases are known for their stability and lack of reactivity due to having a full valence shell.

2. **Understand Atomic Structure**:
- Noble gas atoms have complete outer electron shells, which makes them stable. This stability means that there is minimal interaction between the atoms of noble gases.

3. **Nature of Forces**:
- The primary forces present in noble gas atoms are very weak intermolecular forces known as London dispersion forces (or van der Waals forces). These forces arise due to temporary fluctuations in electron density that create instantaneous dipoles.

4. **Characteristics of London Forces**:
- London dispersion forces are the weakest type of intermolecular force and are present in all atoms and molecules, but they are particularly significant in noble gases due to their nonpolar nature. These forces increase with the size of the atom, as larger atoms have more electrons and a greater polarizability.

5. **Conclusion**:
- In summary, the forces present in noble gas atoms are primarily London dispersion forces, which are very weak and result from temporary dipoles. This weak interaction is consistent with the overall stability and non-reactivity of noble gases.

### Final Answer:
The nature of the forces present in noble gas atoms is primarily very weak London dispersion forces.
