Detailed explanation-1: -Given the electronegativity of rubidium is 0.8 and of chlorine is 3.0, our best interpretation of a bond between these two elements would be. No worries!
Detailed explanation-2: -The typical rule is that bonds with an electronegativity difference less than 1.6 are considered polar.
Detailed explanation-3: -The first scale of electronegativity was developed by Linus Pauling and on his scale rubidium has a value of 0.82 on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine).
Detailed explanation-4: -A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond.
Detailed explanation-5: -The electronegativity of K = 0.8 and Cl = 3.0.
