How does the periodic table substantiate atomic theory?
A)Both are theoretical and cannot support each other.
B)Groups in the periodic table have similar properties based on similar features of atomic structure, namely, the same number of valence electrons per atom.
C)All elements in a given period of the periodic table have the same number of valence electrons.
D)Mendeleev declared consistency between the periodic table and atomic theory.

Question

Quizplus · Accepted Answer

The periodic table helps to substantiate atomic theory by organizing the elements based on their atomic structure, specifically their number of valence electrons. The groups in the periodic table have similar properties because they have the same number of valence electrons in their outermost energy level. This consistency supports the idea that atomic structure and properties are related.
