The most expensive metal in the world
Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.

Interesting facts about metals
Metals have been used by people since ancient times. All the time the process of obtaining them was improved, useful alloys of various metals appeared. Let’s look at interesting facts about metals.
Most Popular
Crystal Field Theory
Theory of bonding in transition metal complexes in which ligands and metal ions are treated as point charges, a purely ionic model, ligand point charges represent the crystal (electrical) field perturbing the metal?s d orbitals containing nonbonding electrons.
Metalloids
Elements with properties intermediate between metals and nonmetals: B, Al, Si, Ge, As, Sb, Te, Po, and At.
Electron Configuration
Specific distribution of electrons in atomic orbitals of atoms or ions.
Saccharate
A compound formed by interaction of sucrose with a metallic oxide, usually lime, and useful in the purification of sugar.
Emulsion
Colloidal suspension of a liquid in a liquid.
K Capture
Absorption of a K shell (n=1) electron by a proton as it is converted to a neutron.
Polymerization
The combination of many small molecules to form large molecules.
Optical Isomers
Stereoisomers that differ only by being nonsuperimposable mirror images of each other, like right and left hands, also called enantiomers.
Nuclides
Refers to different atomic forms of all elements in contrast to ?isotopes?, which refer only to different atomic forms of a single element.
Endothermicity
The absorption of heat by a system as the process occurs.
