Meaning of a dipole

I'm a bit confused, what does the term dipole mean? And is it different from a dipole moment?

Thank you so much! :)

A dipole describes the separation of charges in a molecule of covalently bonded atoms. I'm pretty sure a dipole moment is just the measurement of the separation of those opposite charges.

Hope this helps!

And when you say separation of charges in the molecule do you mean where the electrons are located?
Thank you! :)

I think it is just the charge of that specific atom.

A dipole is a separation of opposite electrical charges. The larger the difference in electronegativity, the greater the dipole moment.

So if there is a greater dipole moment, does the molecule have a stronger ionic bond? And is its potential energy greater?

A dipole occurs between two covalently bonded atoms where one is more electronegative than the other. This difference creates a separation of electrical charges

Answering Victoria’s question, if there is a greater dipole moment, then yes the molecule has a stronger ionic bond between its atoms. I would think that its potential energy wouldn’t necessarily be greater, as the weakest bond, Van Der Waals, has the greatest potential energy out of all bonds/interactions
