If you are talking about covalent bonded molecules, then you would call them polar molecules. This means one element is hogging the shared electrons more than the other.
This would make one element partially charged positively, and the other element partially charged negatively
The signs to show partially charged looks like an incomplete 8.

polar molecule
First there are three sides of a molecule there are 2 hydrogen sides and 1 oxygen side. The oxygen end has a slight negative charge, and the hydrogen end has positive charge. A molecule that has electrically charged areas is a polar molecule. Because water consists of polar water molecules, it is called a polar substance.
Osmosis is not a molecule. It is the flow of water through cell membranes from areas of high concentration to areas of low concentration.
"A type of covalent bond between two atoms in which electrons are shared unequally" In water you have dissociation into H+ and OH-. However in terms of polar and non polar, the key thing is that You have an oxygen there (specifically OH), and no hydrocarbon backbone that would make it non-polar
quick answer is that nucleophiles like positive areas of molecules and electrophiles like negative areas of a molecule. In methane (CH4) the hydrogen and carbon have similar electronegativities and therefore there are no real positive and negative centres. Hope this helps mate

hi

Electromagnetism is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields.
The phenomenon that describes the movement of any kind of molecule from areas of higher concentration to areas of lower concentration is called diffusion.
Molecules tend to move into areas where there are less molecules. This is called diffusion and can happen with or without energy.
Such areas are called Van Allen belts.
The oxygen atom is much more electronegative than the hydrogen atoms, meaning that it draws the electrons toward it more than the hydrogen atoms do. this causes a dipole moment, meaning that the molecule, even though it is neutral overall, has areas where there is a greater electron density than other areas of the molecule. the shared electrons spend a disproportionately high amount of time around the oxygen atom than they do around the hydrogen atoms, making the oxygen a negatively charged region and the hydrogens a positively charged region.
The movement of molecules from an area of high concentration of that molecule to an area of lower concentration is called simple diffusion.

Electric charge! The drum is coated with a photo-conductive layer, whose electrical resistance changes when exposed to light. In the old days this was based on selenium, but nowadays it uses an organic plastic compound. First the drum is electrically charged using a 'corona wire' - a very fine wire grid at high voltage. Then a laser (or, these days, an LED array) is used to expose the 'white' areas, causing electric charge to leach away in those areas. Next toner (which is itself tumbled to build up an electric charge) is brushed over the drum, so that it sticks only to the electrically charged ('black') areas on the drum. It's then a simple matter to get the toner off the drum and onto the paper. Finally the drum is cleaned with a brush and/or wiper blade, and electrically discharged using a 'quench' lamp before the whole process starts again.
