The chemical reaction associated with this method of analysis involves formation of the diiodo alkane (R and R' symbolize alkyl or other organic groups): The precursor alkene (R1CH=CHR2) is colorless and so is the organoiodine product (R1CHI-CHIR2). The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) stabilizes the free metal somewhat against further oxidation.

The difference is a measure of the nuclear binding energy which holds the nucleus together. Cerium is the second element in the lanthanide series.
Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z. Iodine Number, also known as iodine value, iodine index or iodine absorption value is the measure of the unsaturation of a substance which is expressed as grams of iodine or similar halogen absorbed by hundred grams of a substance. The chemical symbol for Thulium is Tm. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs).
