Which of the following depicts the Modern Periodic Table?

The correct answer is d.

The Modern Periodic Table is constructed based on the Modern Periodic Law, which states that the properties of elements are periodic functions of their atomic numbers.
The structural framework of the Modern Periodic Table is defined by two key parameters:
1. Vertical Columns (Groups): There are 18 vertical columns numbered from 1 to 18.
2. Horizontal Rows (Periods): There are 7 horizontal rows numbered from 1 to 7.

By observing the given image:

• Diagram a incorrectly shows only 6 periods and groups up to 15.
• Diagram b incorrectly shows only 6 periods and groups up to 16.
• Diagram c incorrectly shows groups up to 17.
• Diagram d correctly shows all 7 periods (numbered 1 through 7) and all 18 groups (numbered 1 through 18).

Therefore, diagram d accurately depicts the structure of the Modern Periodic Table.
