The correct response is: So that elements with similar properties are aligned in the same column.

The gaps in the periodic table represent undiscovered elements that fit within the structure of the table based on their predicted properties and behaviors. The arrangement is primarily based on atomic number and similarities in chemical properties, not simply mass or size.
