Ionic and Covalent Bonds and Electrons

Postby DTingey_1C » Sun Oct 27, 2019 8:14 pm

When ionic or covalent bonds are formed, does the "probability area" of an atom's e- shift toward the atom it is sharing e- with (or giving e- to)? If so, how is it effected by the bond?

I'm just gonna assume that by "probability area" you mean the likelihood of finding an electron in a given area

In an ionic bond, since one atom is electronegative enough to completely steal an electron, you should expect that the "probability area" has shifted towards the anion, and shifted away from the cation.

The logic is similar in covalent bonds as well, if one atom is more electronegative, the electrons will spend more time around it, but will also spend time around the less electronegative atom as well. In any case, the probability also shifts towards the more electronegative atom, but in the same intensity as if it were an ionic bond.

In an ionic bond, one atom removes an electron from another atom, so you will be more likely to find an electron near the more electronegative atom (anion).

Covalent bonds can either be polar or nonpolar- in polar covalent bonds, it is more likely to find an electron near the more electronegative atom. In nonpolar covalent bonds, the two atoms have similar electronegativities and will share electrons equally.

Dr. Lavelle said in lecture that p-block non-metals form anions and gain p valence electrons until the following noble gas electron configuration is reached. Can anyone explain this?
