Question

5/7
how can you determine if a bond is ionic using electronegativity differences?
if the difference is between 0.5 and 1.7 if the difference is less than 0.5
if the difference is greater than 1.7 if the difference is exactly 1.0

Explanation:

Electronegativity difference helps classify bonds. For ionic bonds, the rule of thumb is that if the electronegativity difference between two atoms is greater than 1.7, the bond is considered ionic. This is because a large electronegativity difference means one atom has a much stronger pull for electrons than the other, leading to electron transfer (characteristic of ionic bonds). A difference between 0.5 - 1.7 is a polar covalent bond (unequal electron - sharing), less than 0.5 is non - polar covalent (equal or near - equal electron - sharing), and exactly 1.0 is just a value within the range of possible differences but not the criterion for ionic.

Answer:

If the difference is greater than 1.7
