Relating Functional Groups to the Periodic Table

Journal of Chemical Education, 2009
An introduction to organic chemistry functional groups and their ionic variants is presented. Functional groups are ordered by the position of their specific (hetero) atom in the periodic table. Lewis structures are compared with their corresponding condensed formulas.

Peroxides of the Group Two Elements of the Periodic Table

1966
All elements of the second group, with the exception of beryllium [1], form peroxide compounds. Peroxides of calcium, strontium, and barium belong to the M2+O2 2- type; while peroxides of magnesium, zinc, and cadmium, of general formula MO2 • xH2O, probably belong to the HO—M—OOH type where the covalent bond between the hydroperoxyl group and the metal

The group VIII platinum-group metals and the Periodic Table

Foundations of Chemistry, 2009
The six platinum group metals (pgms: ruthenium, rhodium, palladium, osmium, iridium and platinum) posed a number of problems for 19th-century chemists, including Mendeleev, for their Periodic classification. This account discusses the discovery of the pgms, the determination of their atomic weights and their classification.

Peroxides of the Group One Metals of the Periodic Table

1966
All alkali metals form peroxides. The peroxides of all the alkali metals, with the exception of lithium, can be synthesized by direct oxidation of the metal with oxygen at atmospheric pressure. The reactivities of sodium, potassium, rubidium, and cesium result from the fact that these metals have large atomic radii and low ionization potentials ...
