Dipole
Todays lecture ended with the introduction of Dipole, how do you represent dipole with an arrow if two atoms are very similar in electronegativity? Will this ever be the case or will one always be more electronegative than the other?

Re: Dipole
I think one will always be at least slightly more electronegative than the other; if they're the same element (like N2) then there wouldn't be any dipole moments because they would have equal electronegativity, i'm not totally sure though.
Re: Dipole
Hi ! This was discussed in relation to polar covalent bonds. In these types of bonds, one atom will always be more electronegative than the other(s), giving a separation of charge. In this case you could draw the arrow showing the direction of the dipole/dipole moment. A nonpolar covalent bond has a very small difference in electronegativity, or no difference at all. An example would be O2. Because the O atoms have the same electronegativity, you couldn't distinguish where the probable "pooling" of electrons would be.

Re: Dipole
Dipole has to do with polar covalent bonds! This means that one of the atoms will always be more electronegative, and in turn you will be able to draw the arrow without worrying about the atoms being too close in electronegativity.
