hydrogen bond
Water's cohesive force
A hydrogen bond is a weak attraction between a hydrogen atom bonded to an electronegative atom (like oxygen or nitrogen) and another electronegative atom nearby.
Though individually weak, hydrogen bonds collectively produce significant effects: they give water its unusual properties, hold DNA's double helix together, and shape protein structures.
Hydrogen bonds between water molecules explain why ice floats.
The term also functions as a verb: molecules can hydrogen bond to each other.
