Atomic number of `Ag` is 47. in the same group, the atomic numbers of elements placed above and below `Ag` in Long form of periodic table will be:

Options

A. 26, 95
B. 39,79
C. 29,79
D. 39,65

Explanation

To solve the question regarding the atomic numbers of elements placed above and below silver (Ag) in the long form of the periodic table, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Atomic Number of Silver (Ag)**:
- The atomic number of silver (Ag) is given as 47.

2. **Determine the Element Above Silver**:
- In the periodic table, elements in the same group have similar properties and a specific pattern in their atomic numbers.
- For transition metals, the atomic number of the element directly above silver can be found by subtracting 18 from the atomic number of silver.
- Calculation:
\[ \text{Atomic number above Ag} = 47 - 18 = 29 \]
- The element with atomic number 29 is copper (Cu).

3. **Determine the Element Below Silver**:
- To find the atomic number of the element directly below silver, we typically add 18 to the atomic number of silver.
- Calculation:
\[ \text{Atomic number below Ag} = 47 + 18 = 65 \]
- However, the element with atomic number 65 is terbium (Tb), which is an inner transition metal and does not belong to the same group as silver.
- Instead, we need to add 32 to the atomic number of silver to find the correct element below it in the periodic table.
- Calculation:
\[ \text{Atomic number below Ag} = 47 + 32 = 79 \]
- The element with atomic number 79 is gold (Au).

4. **Final Answer**:
- The atomic number of the element above silver (Ag) is 29 (copper, Cu).
- The atomic number of the element below silver (Ag) is 79 (gold, Au).

### Summary:
- **Above Ag (Cu)**: Atomic number = 29
- **Below Ag (Au)**: Atomic number = 79
