Water Molecule
The bent little molecule that makes life possible/Scientific Objects
A single water molecule (H2O) is about 2.75 angstroms across and has a distinctive 104.5-degree bond angle that gives it a permanent electric dipole. This simple geometry is responsible for ice floating, water being an excellent solvent, and essentially all of biology. A single glass of water contains about 8.36 x 10^24 of these molecules.
