Name the block in which metals, metalloids, non-metals and inert gases all are present

Options

A. s-block
B. p-block
C. d-block
D. f-block

Explanation

To answer the question, "Name the block in which metals, metalloids, non-metals, and inert gases all are present," we can follow these steps:

### Step 1: Understand the Classification of Elements
Elements in the periodic table are classified into different blocks based on their electron configurations. The main blocks are:
- S-block
- P-block
- D-block
- F-block

### Step 2: Analyze Each Block
- **S-block**: Contains only metals (alkali and alkaline earth metals).
- **D-block**: Contains transition metals, which are all metals.
- **F-block**: Contains lanthanides and actinides, which are also metals.

### Step 3: Identify the P-block
- **P-block**: This block includes a variety of elements:
- **Metals**: Present in groups 13 to 16 (e.g., aluminum, tin, lead, bismuth).
- **Metalloids**: Elements like boron, silicon, germanium, arsenic, antimony, and tellurium.
- **Non-metals**: Elements like carbon, nitrogen, oxygen, phosphorus, sulfur, and selenium.
- **Inert Gases**: Noble gases such as helium, neon, argon, krypton, and xenon.

### Step 4: Conclusion
Since the P-block contains metals, metalloids, non-metals, and inert gases, it is the block that includes all four categories of elements.

### Final Answer
The block in which metals, metalloids, non-metals, and inert gases all are present is the **P-block**.
