Element corresponding to which of these//this atomic number belongs to p-block in Modern Periodic Table:

Options

A. 19
B. 35
C. 53
D. 83

Answer

To determine which elements correspond to the given atomic numbers and belong to the p-block of the modern periodic table, we can follow these steps:

### Step 1: Identify the Atomic Numbers
The question provides us with four atomic numbers: 19, 35, 53, and 83. We need to analyze each of these numbers to see which elements they correspond to.

### Step 2: Find the Elements for Each Atomic Number
- **Atomic Number 19**: This corresponds to Potassium (K).
- **Atomic Number 35**: This corresponds to Bromine (Br).
- **Atomic Number 53**: This corresponds to Iodine (I).
- **Atomic Number 83**: This corresponds to Bismuth (Bi).

### Step 3: Determine the Block of Each Element
In the modern periodic table:
- The **p-block** includes elements from groups 13 to 18.
- The **s-block** includes groups 1 and 2.

Now, we categorize the elements based on their group:
- **Potassium (K)**: Group 1 (s-block)
- **Bromine (Br)**: Group 17 (p-block)
- **Iodine (I)**: Group 17 (p-block)
- **Bismuth (Bi)**: Group 15 (p-block)

### Step 4: Conclusion
From our analysis:
- The elements that belong to the p-block are Bromine (35), Iodine (53), and Bismuth (83).
- The element Potassium (19) does not belong to the p-block.

Thus, the atomic numbers that correspond to elements in the p-block are **35, 53, and 83**.

### Final Answer
The elements corresponding to atomic numbers 35, 53, and 83 belong to the p-block in the modern periodic table.
