it is an ionic bond for sure

Sofia Hudson · Answer 2

According to the electronegativity table, whenever there a difference of more than 2.0 then the bond formed will be ionic in nature. On the other hand, if electronegativity difference is less than 0.5 then the bond formed will be non-polar covalent in nature.

Since, we are given electronegativity of both elements X and Y. Hence, the difference of their electronegativity is as follows.

Electronegativity difference = 3.30 - 3.25

= 0.05

Therefore, it means that the molecule XY must be a non-polar covalent compound.
