Why are there empty spaces in the rows on the periodic table? (1 point)

Question

So that elements with similar properties are aligned in the same column.

Because elements of the same size are found in the same rows.

So that elements with similar masses are right next to each other.

Because the elements on the periodic table are arranged by order of discovery.

Answer 1

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

The empty spaces in the periodic table represent elements that have not yet been discovered or synthesized, but they are intentionally placed to maintain the organization of elements according to their properties and to ensure that similar elements are grouped together in the same columns (groups).
