why are there empty spaces in the rows on the periodic table?(1 point)ResponsesBecause elements of the same size are found in the same rows.Because elements of the same size are found in the same rows.Because the elements on the periodic table are arranged by order of discovery.Because the elements on the periodic table are arranged by order of discovery.So that elements with similar properties are aligned in the same column.So that elements with similar properties are aligned in the same column.So that elements with similar masses are right next to each other.So that elements with similar masses are right next to each other.

Answer 1

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

The periodic table is arranged by atomic number with elements grouped in columns (groups) based on their similar chemical properties, which sometimes results in empty spaces when an element has not yet been discovered or when certain patterns or periodic trends are observed.
