Question

physical science a semester exam
how did the study of the atom contribute to our understanding of the periodic table of the elements? (1 point)
experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the 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.
the determination of electron charge led to an understanding of how atoms interact with one another, which facilitated 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.

Explanation:

The study of atoms gave atomic weights and numbers through experiments. These were key in organizing the periodic table. The other options are either incorrect or less directly related to the organization of the periodic table based on atomic - level understanding.

Answer:

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