Which of the following groups contains metals.non-metals and metalliods?

Options

A. Group17
B. Group 14
C. Group 13
D. Group 12

Explanation

To determine which of the following groups contains metals, non-metals, and metalloids, we will analyze each group one by one.

### Step-by-Step Solution:

1. **Identify the Groups:**
The groups to analyze are Group 17, Group 14, Group 13, and Group 12.

2. **Analyze Group 17:**
- Group 17 consists of the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
- All these elements are non-metals.
- **Conclusion:** Group 17 does not contain metals or metalloids.

3. **Analyze Group 14:**
- Group 14, also known as the carbon family, includes: carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb).
- Here, carbon and silicon are non-metals, germanium is a metalloid, and tin and lead are metals.
- **Conclusion:** Group 14 contains metals, non-metals, and metalloids.

4. **Analyze Group 13:**
- Group 13, known as the boron family, includes: boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
- Boron is a metalloid, while aluminum, gallium, indium, and thallium are metals.
- **Conclusion:** Group 13 does not contain non-metals.

5. **Analyze Group 12:**
- Group 12 consists of: zinc (Zn), cadmium (Cd), and mercury (Hg).
- All these elements are metals.
- **Conclusion:** Group 12 does not contain non-metals or metalloids.

6. **Final Conclusion:**
- After analyzing all the groups, we find that only **Group 14** contains metals, non-metals, and metalloids. Therefore, the correct answer is **Group 14**.
