Asked by lyne

how would you determine the % of ionic/covalent char. in the bond?

this is on my test review and don't remember learning it

You look up the electronegativity of each element and subtract one from the other. Then do one of the following:
a. Look up the percent ionic/covalent character from a table or graph OR
b. Knowing that a difference of about 1.9 is about 50% ionic/50% covalent character, make an estimate. For example, if the difference is 1.0, then knowing about 2.0 is 50/50 and a difference of 0 is 100% covalent, then 1.0 must be pretty close to 25% ionic/75% covalent character.
