  Group 6 element - Wikipedia, the free encyclopedia
A Group 6 element is the series of elements in group 6 (IUPAC style) in the periodic table, which consists of the transition metals chromium (Cr), molybdenum (Mo), tungsten (W), and seaborgium (Sg).
"Group 6" is the new IUPAC name for this group, the old style name was "group VIA" in the old European system or "group VIB" in the old US system.
Group 6 must not be confused with the group with the old-style group names of either VIB (European system) or VIA (US system) which is now group 16.

 Group Theory   (Site not responding. Last check: 2007-10-16)
When a group is in fact commutative - i.e., for all a and b in the group one has a#b = b#a - then it is said to be an Abelian group.
The order of this group is 8 - that is, G Consider the set H = {2, 2#2, 2#(2#2), 2#(2#(2#2)),......}, a subset of G. Doing the indicated computations shows that H = {2, 4, 8, 1}, and one can check that indeed (H,#) is a subgroup of (G,#).

 Phosphorus   (Site not responding. Last check: 2007-10-16)
Phosphorus, (from the Greek language Phosphoros meaning "light bearing"), is the chemical element in the periodic table that has the symbol P and atomic number 15.
A multivalent, nonmetal of the nitrogen group, phosphorus is commonly found in inorganic phosphate rocks and in all living cells.
This is a particularly poisonous element with 50 mg being the average fatal dose (white phosphorus is generally considered to be the lethal form of phosphorus while phosphate and orthophosphate are essential nutrients).

The task group also responded to two interpretation requests submitted on the subjects of unknown values in a received information element and conflict between clause 9 and annex C on the use of rery counters.
As a result, the task group directed the editor to produce a draft of the revision of the standard, including 802.11-1999, 802.11a, 802.11b, 802.11b-Cor1, 802.11d, 802.11g, and 802.11h, as well as the items completed during the meeting.

 Antimony   (Site not responding. Last check: 2007-10-16)
Antimony in its elemental form is a silvery white, brittle, fusible, crystalline solid that exhibits poor electrical and heat conductivity properties and vaporizes at low temperatures.
The origin of the name "antimony" is not clear; the term may come from the Greek words "anti" and "monos", which approximately means "opposed to solitude" as it was thought never to exist in its pure form, or from the Arabian expression "Antos Ammon", which could be translated as "bloom of the god Ammon".
Even though this element is not abundant, it is found in over 100 mineral species.

The metadata elements fall into three groups which roughly indicate the class or scope of information stored in them: (1) elements related mainly to the Content of the resource, (2) elements related mainly to the resource when viewed as Intellectual Property, and (3) elements related mainly to the Instantiation of the resource.
While it is generally recommended that elements contain information about the present resource only, this element may contain metadata for the second resource when it is considered important for discovery of the present resource.
