D
Nitrogen (N)
Verified step by step guidance1
Identify the position of oxygen in the periodic table. Oxygen is in Group 16 (the chalcogens) and Period 2.
Recall that elements in the same group (vertical column) of the periodic table have similar chemical properties because they have the same number of valence electrons.
Check which of the given elements belong to Group 16. Sulfur (S) is in Group 16, just below oxygen, so it has similar chemical properties.
Sodium (Na) is in Group 1, Fluorine (F) is in Group 17, and Nitrogen (N) is in Group 15, so they do not share the same group as oxygen and thus have different chemical properties.
Conclude that sulfur (S) would have chemical properties most similar to oxygen due to their shared group and valence electron configuration.
