Normally hydrogen is placed in

Options

A. IA
B. IVA
C. VIIA
D. All of these

Answer

To answer the question "Normally hydrogen is placed in", we will analyze the properties of hydrogen and its position in the periodic table step by step.

### Step-by-Step Solution:

1. **Identify the Atomic Number and Configuration of Hydrogen**:
- Hydrogen has an atomic number of 1.
- Its electronic configuration is 1s¹, meaning it has one electron in its outermost shell.

2. **Determine the Group Based on Electron Configuration**:
- Since hydrogen has one electron in its outermost shell, it behaves similarly to alkali metals, which are found in Group 1 of the periodic table. Alkali metals also have one electron in their outermost shell.

3. **Consider the Properties of Hydrogen**:
- Hydrogen is the lightest element in the periodic table.
- It can lose one electron to form a cation (H⁺), similar to how alkali metals lose one electron to form cations.

4. **Placement in the Periodic Table**:
- Based on its properties and electronic configuration, hydrogen is normally placed in Group 1 of the periodic table, which is also referred to as Group 1A.

5. **Conclusion**:
- Therefore, the answer to the question is that hydrogen is normally placed in Group 1A of the periodic table.

### Final Answer:
Hydrogen is normally placed in Group 1A of the periodic table.
