Answer

To determine the conductivity values of MnO (manganese oxide), we will analyze its properties as a transition metal oxide and categorize its conductivity.

### Step-by-Step Solution:

1. **Identify the Type of Compound**:
- MnO is a transition metal oxide, specifically an oxide of manganese.

2. **Understand the Conductivity of Transition Metal Oxides**:
- Transition metal oxides, particularly those in the 3d series, are generally known to exhibit insulating properties. This is due to their electronic structure, which does not allow for easy movement of electrons.

3. **Classify MnO**:
- Since MnO is a 3d transition metal oxide, it falls under the category of insulators. Therefore, we can conclude that MnO will have very low conductivity.

4. **Determine the Range of Conductivity**:
- The conductivity of insulators is typically very low, often in the range of \(10^{-10}\) to \(10^{-22}\) ohm\(^{-1}\) cm\(^{-1}\). This indicates that MnO has negligible conductivity.

5. **Compare with Other Conductivity Ranges**:
- For context, semiconductors have conductivity values ranging from \(10^{-6}\) to \(10^{4}\) ohm\(^{-1}\) cm\(^{-1}\), and conductors have values from \(10^{3}\) to \(10^{8}\) ohm\(^{-1}\) cm\(^{-1}\). This further confirms that MnO, being an insulator, has a significantly lower conductivity than both semiconductors and conductors.

### Final Answer:
The conductivity values in MnO are in the order of \(10^{-10}\) to \(10^{-22}\) ohm\(^{-1}\) cm\(^{-1}\).
