Which contributes to the polarity of a water molecule?

Oxygen and two hydrogen molecules

Explanation:

Polarity simply implies a molecules with positive and negatively charged ends.

The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds.

While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction.

im back lol i heard you where asking for me

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
