Verified step by step guidance

Understand that the periodic table is arranged in rows called periods (horizontal) and columns called groups (vertical).

Recognize that elements in the same group have the same number of valence electrons, which largely determines their chemical properties.

Recall that elements with similar atomic masses or consecutive atomic numbers do not necessarily have similar chemical properties because their electron configurations differ.

Note that elements in the same period have the same number of electron shells but different numbers of valence electrons, leading to different chemical behaviors.

Conclude that the group (vertical column) arrangement best predicts similarity in chemical properties because of the shared valence electron configuration.
