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.

Alkenes (Olefins)

Unsaturated hydrocarbons that contain one or more carbon-carbon double bonds.

Single Bond

Covalent bond resulting from the sharing of two electrons (one pair) between two atoms.

Active Metal

Metal with low ionization energy that loses electrons readily to form cations.

Debye

The unit used to express dipole moments.

Accuracy

How closely a measured value agrees with the correct value.

Dipole
