Allotropes have the same.....................properties and different.....................

Answer

To answer the question "Allotropes have the same.....................properties and different.....................", we can follow these steps:

### Step 1: Understand the Definition of Allotropes
Allotropes are different forms of the same element that exist in the same physical state but have different structures and properties.

### Step 2: Identify the Properties of Allotropes
Allotropes of an element have:
- **Same Chemical Properties**: This means they react in the same way chemically.
- **Different Physical Properties**: This refers to differences in appearance, hardness, melting point, and other physical characteristics.

### Step 3: Use an Example
For instance, carbon has two well-known allotropes: graphite and diamond.
- **Graphite** has a slippery feel, is opaque, and conducts electricity.
- **Diamond** is hard, transparent, and does not conduct electricity.

### Step 4: Fill in the Blanks
Based on the understanding from the previous steps:
- Allotropes have the same **chemical** properties and different **physical** properties.

### Final Answer
Allotropes have the same **chemical** properties and different **physical** properties.
