Chalocogen used in vulcanisation of rubber is ____.

Answer

To solve the question "Chalcogen used in vulcanization of rubber is ____," we can follow these steps:

### Step 1: Understand the term "Chalcogen"
Chalcogens are the elements found in Group 16 of the periodic table. This group includes oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po).

**Hint:** Remember that "chalcogen" refers to elements in Group 16, often associated with ores and compounds.

### Step 2: Identify the process of vulcanization
Vulcanization is a chemical process that involves heating rubber with sulfur. This process converts natural rubber into a more durable and elastic form by creating cross-links between the rubber molecules.

**Hint:** Think about what substances are commonly used to enhance the properties of rubber.

### Step 3: Determine which chalcogen is used in vulcanization
Among the chalcogens, sulfur is specifically known for its role in the vulcanization process. When rubber is heated with sulfur, it forms a cross-linked structure, which improves the strength and elasticity of the rubber.

**Hint:** Focus on the specific chalcogen that is widely recognized for its application in rubber processing.

### Step 4: Conclude the answer
Based on the information gathered, the chalcogen used in the vulcanization of rubber is sulfur.

**Final Answer:** Sulfur
