Which of these molecules have the strongest ionic bond? KI, KBr, RbCl, RbF?

Answer 1

RbF

you have to look the bigger electronegativity difference. F is the most elettronegative element (4.0 in Pauling scale). Rb one of the less electronegative ones (0,8 in Pauling scale). the difference is 3,2 one of the biggest possible
