Chapter 02 of 5
The Geometry of Cold
Discover the molecular architecture of the hexagonal lattice.
- Microscopic Origin
The V-Shaped Architect
A single water molecule is a bent structure, with two hydrogen atoms flanking one oxygen atom at a specific angle.
- Chemical Bond
Polar Attraction
Oxygen is greedy for electrons, leaving the hydrogen atoms with a slight positive charge that seeks a negative neighbor.
- Mechanism
The Hydrogen Bond
This weak electrostatic attraction acts like a temporary handshake between molecules, constantly breaking and reforming in liquid water.
