Question

19 multiple choice 1 point select the most electronegative atom. cl se sb pb

Explanation:

Electronegativity increases across a period and decreases down a group on the periodic table. Chlorine (Cl) is in group 17, selenium (Se) in group 16, antimony (Sb) in group 15 and lead (Pb) in group 14. Also, Cl is higher up in the periodic table compared to the others. So Cl has the highest electronegativity among them.

Answer:

A. Cl
