Observed similarities of the chemical properties in the elements listed in each column of the periodic table are due to
A) the similarity in the electron configurations.
B) the same z component of the orbital angular momentum.
C) the same value of n for these elements.
D) Hold on. All of the above answers are correct.

Question

Quizplus · Accepted Answer

The chemical properties of elements are primarily determined by their electron configurations, particularly the configuration of the valence electrons. Elements in the same column (group) of the periodic table have similar valence electron configurations, which accounts for their similar chemical properties. Options B and C do not directly explain the observed similarities in chemical properties based on the periodic table's organization.
