That is, despite Ostwald's professed allegiance to the Composition Thesis, his discussions of chemical energy are all couched in terms of the Containment Thesis. He viewed chemical systems as made up of various substances — chemical elements or compounds — and as containing various sorts of ...
Its box is situated at the top of Group 1 in the periodic table, but it is not generally considered a member of the alkali family, the other elements that make up Group 1. Its chemical properties are unique among the elements, and it is usually considered to be in a family of its ...

Ionic forms of elements are important to the body, as they are able to conduct electricity when dissolved in water. These ions are calledelectrolytes. Single atoms, or atoms that are covalently linked in molecules can undergo ionization. See examples below. ...
“the rocks provide a stable matrix and a micro-porous medium in which active components are able to act as a water purifying agent through ion exchange” and “Dog Rocks will help purify the water by removing some nitrates, ammonia and harmful trace elements thereby giving your dog a ...
metallic elements of groups V, VI, and VII of the MVendeleeff Periodic System, beneficially influence the phenolates by increasing their potentency for stabilizing the lubricating oils and by making the phenolates, in themselves, more stable, as for instance, against hydrolysis....
