Question

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

Answer 1

Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.

Brief reason: early periodic order used atomic (relative) masses; later the discovery of the proton/atomic number gave the correct, modern ordering and explained periodicity.
