Question

Between the elements- N, O, P, and S; the one with the maximum electronegativity is :

• A. N
• B. O
• C. P
• D. S

Answer 1

The correct option is B

O

• Electronegativity means the tendency of an atom to attract a shared pair of electron.
• Electronegativity increases across a period and decreases down the group.
• In these four elements, Nitrogen (N) and Oxygen (O) are in period 2, and Phosphorous (P) and Sulfur (S) are in period 3.
• So elements in period 2 have more electronegativity. Among Nitrogen(N) and Oxygen(O), Oxygen(O) is on the right side of the table.
• Hence, Oxygen (O) has the maximum electronegativity among these four elements.
