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 the group in which oxygen (O) is located. Oxygen is in Group 16, also known as the chalcogens.
Look for the element among the options that is also in Group 16, meaning it has the same number of valence electrons as oxygen.
Check each option: Chlorine (Cl) is in Group 17, Sodium (Na) is in Group 1, Neon (Ne) is in Group 18, and Sulfur (S) is in Group 16.
Conclude that Sulfur (S) is the element most likely to have chemical properties similar to oxygen because it is in the same group on the periodic table.
