Allotropy - Wikipedia

Allotropy or allotropism (from Ancient Greek ἄλλος (allos) ''other'', and τρόπος (tropos) ''manner, form'') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements. Allotropes are different structural modifiions of an element; the atoms of the element are bonded together in a different manner.

Substance (Stanford Encyclopedia of Philosophy)

Oct 03, 2004· The elimination of matter as a good candidate for being substance, leaves either form alone or the composite of form and matter. The composite seems more consonant with the doctrine of egories, for the composite is the individual. Aristotle, however, chooses the form as more paradigmatically substance. This has puzzled some commentators.

Silver - Periodic table

Silver has a special place in the history of the elements because it is one of the first five metals discovered and used by humans. The others were gold , copper , lead and iron . Silver objects dating from before 4000 BC have been found in Greece and from slightly later in Anatolia (in modern Turkey).

18.1 Periodicity – Chemistry

The group 12 elements behave more like the alkaline earth metals than transition metals. Group 12 contains the four elements zinc, cadmium, mercury, and copernicium. Each of these elements has two electrons in its outer shell (ns 2). When atoms of these metals form ions with a charge of 2+, where the two outer electrons are lost, they have pseudo-noble gas electron configurations.

Metals, Metalloids, and Nonmetals - Angelo State University

The main-group metals usually form charges that are the same as their group nuer: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges. The metals which follow the transition metals (towards the bottom of Groups 4A and 5A) can lose either …

Coordination Complexes and Ligands

Other ligands can attach to the metal more than once. Ethylenediamine (en) is a typical bidentate ligand. Each end of this molecule contains a pair of nonbonding electrons that can form a covalent bond to a metal ion. Ethylenediamine is also an example of a chelating ligand. The term chelate comes from a Greek stem meaning "claw." It is used to

Solved: Which Of The Following Are True? [check All That A

Ternary compound consists of two elements. Most transition metals and the metals of group 3A (except Al), 4A, and 5A exhibit more than one oxidation state, thus, they may form two or more binary compounds with the same nonmetals. Ternary acids are compounds of hydrogen, oxygen and (usually) a metal.
