Polar vs covalent

Postby 405404782 Gabriel Rigole 4F » Sun Nov 10, 2019 8:10 pm

How to tell if a bond is polar covalent or ionic without looking at ionization energies?

Usually, you can tell by which elements are in the bond, especially for ionic when an element likely to form cations is bonded to one that's likely to form anions. You can also tell with the differences in electronegativity as well.

You can tell if a bond is ionic if the two elements involved have a large difference in electronegativity. Basically, you can just look at the periodic table and if the two elements are on far, opposite ends, it is likely ionic.

Adding on to this, if two elements are on opposite sides of one another on the periodic table, they most likely will be ionic due to the size as well since the bigger element would be dominating the bond over the smaller one

Ionic bonds involve the transfer of electrons from one element to another while covalent results from the sharing.

Covalent bonds occur between two nonmentals, while ionic bonds occur between a metal and a nonmetal.

does this infer that polar and ionic are interchangeable? You have me a little confused.

You can use general trends of electronegativity in the periodic table.
