Which describes the polarity in a water molecule? partial negative charge on the oxygen atom because its electrons are pulled toward the hydrogen atoms partial negative charge on the oxygen atom because it pulls electrons from the hydrogen atoms partial positive charge on the oxygen atom because it pulls electrons from the hydrogen atoms partial positive charge on the oxygen atom because its electrons are pulled toward the hydrogen atoms

The mechanism of development of partial negative charge on oxygen atom because it pulls electrons from hydrogen atoms gives best description about the polarity in a water molecule.

One of water's significant properties is that it is made out of polar atoms. The two hydrogen particles and one oxygen iota inside water atoms structure polar covalent bonds. While there is no net charge to a water particle, the extremity of water makes a somewhat positive charge on hydrogen and a marginally negative charge on oxygen, adding to water's properties of combination.  

Water's charges are produced in light of the fact that oxygen is increasingly electronegative, or electron adoring, than hydrogen. In this way, all things considered, a common electron would be found close to the oxygen core than the hydrogen core.

Since, water is a nonlinear or bowed particle, the distinction in electronegativities between the oxygen and hydrogen molecules creates the fractional negative charge close to the oxygen and halfway positive charges close to the hydrogen.
