Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length.

Classic magnetic alloys based on iron and other ferromangetic materials feature metallic bonding, with all atoms essentially bonded to all nearest neighbors in the crystal lattice.

Field evaporation is an effect that can occur when an atom bonded at the surface of a material is in the presence of a sufficiently high and appropriately directed electric field, where the electric field is the differential of electric potential (voltage) with respect to distance.

The atoms bonded more tightly than anything we know.

The Dulong-Petit law fails at room temperatures for light atoms bonded strongly to each other, such as in metallic beryllium, and in carbon as diamond.

In 1874, Jacobus Henricus van 't Hoff and Joseph Le Bel discovered the difference was caused by the way that the atoms bonded to carbon in a tetrahedral (four faced) shape.

A polyatomic ion, also known as a molecular ion, is a charged species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit in the context of acid and base chemistry or in the formation of salts.

Dr. Perutz, who had researched hemoglobin for years, used a procedure suggested by Dr. Bernal by which a heavy-metal atom bonded with a protein to serve as a marker.
