Super conductors are derived from compound of:

Options

A. p-block elements
B. lanthanoides
C. actinoides
D. transition elements

Answer

To solve the question "Superconductors are derived from compounds of:", we will follow these steps:

### Step 1: Understand the concept of superconductors
Superconductors are materials that exhibit zero electrical resistance below a certain temperature known as the critical temperature. This means that they can conduct electricity without any energy loss.

**Hint:** Remember that superconductors operate at low temperatures and have unique properties compared to regular conductors.

### Step 2: Identify the role of transition elements
Transition elements (or d-block elements) are known for their ability to conduct electricity well. This is primarily due to the presence of unpaired electrons in their d-orbitals, which allows for the free movement of electrons.

**Hint:** Think about how the structure of transition metals contributes to their conductivity.

### Step 3: Consider the compounds of transition elements
The compounds formed by transition elements often exhibit good electrical conductivity. This is because these compounds can retain the properties of their parent metals, including the ability to conduct electricity.

**Hint:** Focus on the types of compounds that transition metals form and their electrical properties.

### Step 4: Analyze the options provided
If options were given, we would evaluate each one to determine which compounds are derived from transition elements. The correct answer would be the one that indicates a compound of transition elements.

**Hint:** Look for keywords in the options that relate to transition metals or their compounds.

### Conclusion
Based on the understanding that superconductors are derived from compounds of transition elements, the final answer would be that superconductors are derived from compounds of transition elements.

**Final Answer:** Superconductors are derived from compounds of transition elements.
