Peroxides of the Group One Metals of the Periodic Table
1966All 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 ...

Relating Functional Groups to the Periodic Table
Journal of Chemical Education, 2009An 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.

Lanthanides and actinides among other groups of elements of the periodic table
Radiochemistry, 2007The extent to which actinides (An) are similar to other elements of the periodic table is discussed. Actinides show certain similarity with transition metals in trends in variation of the stability of the highest and lowest oxidation states with increasing atomic number.

What Elements Belong in Group 3 of the Periodic Table?
2018The question of precisely which elements should be placed in group 3 of the periodic table has been debated from time to time with apparently no resolution. This question has also received a recent impetus from several science news articles following an article in Nature Magazine in which the measurement of the ionization energy of the element ...

Oxide Adhesion on Periodic Table Group 4 and 5 Metals
1989The oxide scale adhesion on Periodic Table group IV and V metals is evoked through two new concepts in high temperature corrosion: bistability and solute elastic effect.
