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

Question

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.

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

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

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 are intentional, as they represent the gaps for elements that were not yet discovered at the time the table was created. The arrangement of elements is primarily based on their atomic number and properties, ensuring that elements with similar characteristics are grouped in the same columns (or groups).
