Why do Hydrogen Bonds form between Water Molecules?
Oxygen Atoms have a more Positive Charge because they are larger, and have a stronger pull on electrons. Positively Charged O Atoms between Water Molecules are attracted to each other.
Hydrogen Atoms have a more Positive Charge because they are smaller, and have a weaker pull on electrons. Positively Charged H Atoms between Water Molecules are attracted to each other.
Positively Charged Hydrogen Atoms and Negatively Charged Oxygen Atoms between different water molecules are attracted to each other.
Negatively Charged Hydrogen Atoms and Positively Charged Oxygen Atoms between different water molecules are attracted to each other.

Why do Hydrogen Atoms have a Positive Charge in Water Molecules?
Hydrogen Atoms have a stronger pull on electrons. Gaining Electrons = Positive Charge.
Hydrogen Atoms have a weaker pull on electrons. Losing Electrons = Positive Charge.
Hydrogen Atoms have a weaker pull on electrons.
Losing Electrons = Less Electronegative = More Positive.
Hydrogen Atoms are smaller. Having a smaller mass is more positive.

Why do Oxygen Atoms have a more Negative Charge in Water Molecules?
Oxygen Atoms have a stronger pull on electrons. Gaining Electrons = Negative Charge.
Oxygen Atoms have a weaker pull on electrons. Losing Electrons = Negative Charge.
Oxygen Atoms are larger. Having a larger mass = Negative.
Oxygen Atoms lose electrons to Hydrogen Atoms. Losing = Negative.
