What does the arrangement of the periodic table tell scientists
BlackZzzverrR [31]

Answer:

The arrangement of the periodic table leads us to visualize certain trends among the atoms.

Elements are arranged from left to right and top to bottom in order of increasing atomic number.

The rows are called periods. All elements in a row have the same number of electron shells.
