A
Sodium (Na)
B
Chlorine (Cl)
C
Neon (Ne)
D
Oxygen (O)
Verified step by step guidance1
Understand 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.
Identify that sulfur (S) is in Group 16, also known as the chalcogens, which means it has 6 valence electrons.
Look for other elements in Group 16 to find those with similar chemical behavior; these include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po).
Compare the given options (Sodium (Na), Chlorine (Cl), Neon (Ne)) to see which group they belong to: Sodium is in Group 1, Chlorine is in Group 17, and Neon is in Group 18.
Conclude that oxygen (O), which is in Group 16 along with sulfur, is the element most similar in chemical properties to sulfur because they share the same group and valence electron configuration.
