How did the study of the atom contribute to our understanding of the periodic table of the elements?(1 point)
1 Elements are made of atoms, so understanding atoms provided information about elements, which led to the organization of the periodic table.
2 Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.
3 The determination of electron charge led to an understanding of how atoms interact with one another, which facilitated the organization of the periodic table.
4 Atoms are representative of elements, so scientists scaled up atomic characteristics to understand elemental characteristics, allowing scientists to arrange elements in a periodic table.
