Question

Which contributes to the polarity of a water molecule?

Answer 1

The oxygen is negative and the hydrogen is positive, so it has a slightly negative side and a slightly positive side. (like a magnet has opposite ends)

Answer 2

Answer:

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.
