Difference in Electronegativity

Postby joanneyseung22 » Sat Nov 24, 2018 9:17 pm

In Section 3.12, the textbook focuses a lot on figuring out the differences in electronegativity, as well as figuring out the electronegativity given ionization energy and electron affinity. Are these concepts necessary for the upcoming test?

I believe we don't need to memorize the exact electronegativity of elements, but that we should know general trends, as this is useful in figuring out types of bonding or polar/nonpolar molecules.

You're going to need to need to know which elements result in polar or non polar compounds.

Yes, we will have to know what the bonds are based on the electronegativity differences. There should be a chart in our notes that covers this topic, so memorizing it would be good.
