Question

Which of the following elements has highest electronegativity ?

• A. Al
• B. S
• C. Si
• D. P

Answer 1

The correct option is B S

The elements are present in $3^{rd}$ period in the periodic table.On moving across the period from left to right ,the electronegativity increases , because the elements on the right side of the periodic table have more tendency to attract the electron in a bond so as to complete their valence shell of 8 electrons.Thus, S is the most electronegative element.
