Which of the following has strong metallic interactions ? 

Options

A. O
B. Se
C. Se
D. Te

Answer

To determine which of the given elements has strong metallic interactions, we can follow these steps:

### Step 1: Identify the Elements
The elements provided are:
- Oxygen (O)
- Sulfur (S)
- Selenium (Se)
- Tellurium (Te)

### Step 2: Understand the Group
All the elements listed are part of Group 16 of the periodic table, also known as the chalcogens.

### Step 3: Analyze Metallic Character
Metallic character refers to the tendency of an element to lose electrons and form positive ions (cations). In the periodic table:
- **From left to right across a period**: Metallic character decreases.
- **From top to bottom in a group**: Metallic character increases.

### Step 4: Determine the Order of Metallic Character in Group 16
According to the periodic trend:
- Oxygen has the least metallic character.
- Sulfur has more metallic character than oxygen.
- Selenium has more metallic character than sulfur.
- Tellurium has the highest metallic character among these elements.

### Step 5: Conclusion
Since tellurium (Te) is at the bottom of the group and has the highest metallic character, it will exhibit strong metallic interactions.

**Final Answer:** Tellurium (Te) has strong metallic interactions.
