Which of the following statements related to the modern periodic table is incorrect?

Options

A. the p block has 6 column because a max of 6 electron can occupy all the orbits in a p subshell
B. the d block has 8 column because a max of 8 electron can occupy all the orbits in a d subshell
C. each block contains a number of column equal to the number of electrons that can occupy that subshell
D. none of the above

Answer

To determine which statement related to the modern periodic table is incorrect, we will analyze each statement provided.

### Step 1: Understand the Structure of the Modern Periodic Table
The modern periodic table is organized into periods (horizontal rows) and groups (vertical columns). It consists of four blocks: s, p, d, and f, based on the electron configurations of the elements.

### Step 2: Analyze Each Statement
1. **Statement 1**: "P block has 6 corners because maximum 6 electrons can occupy all the orbits in the P subshell."
- **Analysis**: This statement is true. The p subshell can hold a maximum of 6 electrons, corresponding to the 6 columns (or groups) in the p block.

2. **Statement 2**: "D block has 8 corners because maximum 8 electrons can occupy all the orbits in the D subshell."
- **Analysis**: This statement is incorrect. The d subshell can hold a maximum of 10 electrons, corresponding to the 10 columns (or groups) in the d block. Therefore, it should state that the d block has 10 corners, not 8.

3. **Statement 3**: "Each block contains a number of columns equal to the number of electrons that can occupy the subshells."
- **Analysis**: This statement is true. The s block has 2 columns (2 electrons), the p block has 6 columns (6 electrons), and the d block has 10 columns (10 electrons).

### Step 3: Identify the Incorrect Statement
From the analysis, we can conclude that the second statement is incorrect because it misstates the number of corners (columns) in the d block.

### Final Answer
The incorrect statement related to the modern periodic table is: **"D block has 8 corners because maximum 8 electrons can occupy all the orbits in the D subshell."**
