Question

According to a common approximation on the Pauling scale, an electronegativity difference ($\Delta X$) of $1.7$ roughly corresponds to a bond with $50\%$ ionic and $50\%$ covalent character. If the electronegativity of an alkali metal $M$ is $1.3$, what must be the exact electronegativity of a halogen $Y$ to form a bond $M-Y$ that sits exactly at this $1.7$ difference threshold?
