Which of the following elements has the highest electronegativity?
Sulfur (S)
Oxygen (O)
Silicon (Si)
Aluminum (Al)
📝 Detailed explanation
Electronegativity increases across a period and decreases down a group. Oxygen is located in the top right of the periodic table (excluding noble gases) and is more electronegative than Sulfur because its valence electrons are closer to the nucleus.
