Ferrum

Anglo-Saxon, iron L. ferrum) Iron was used prehistorically ... 

Iron [7439-89-6J, Fe, from the Latin ferrum, atomic number 26, is the fourth most abundant element in the earth s cmst, outranked only by aluminum, sihcon, and oxygen. It is the world s least expensive and most useful metal. Although gold, silver, copper, brass, and bron2e were in common use before iron, it was not until humans discovered how to extract iron from its ores that civilization developed rapidly (see Mineral processing and recovery). 

A number of other forms of iron were used, but none gave as good results as the ferrum reductum. ... 

If the complex has an overall negative charge (an anionic complex), the suffix -ate is added to the stem of the metal s name. If the symbol of the metal originates from a Latin name (as listed in Appendix 2D), then the Latin stem is used. For example, the symbol for iron is Fe, from the Latin ferrum. Therefore, any anionic complex of iron ends with -ferrate followed by the oxidation number of the metal in Roman numerals ... 

Name from ferrum (Latin) isara (Celtic) iron (Germanic)... 

The chemical name of compounds composed of only two elements usually ends with the suffix ide. The chemical name for water, for example, which is composed of two atoms of hydrogen and one of oxygen, and whose chemical formula is H20, is, therefore, hydrogen oxide. The chemical name for common table salt, composed of one atom of sodium and one of chlorine, and has the formula is NaCI, is sodium chloride. Pyrite, an iron ore composed of one atom of iron (ferrum in Latin) and one of sulfur, has the formula FeS, and its chemical name is ferrous sulfide. 

The first alloys made by humans were probably those of copper, namely, bronze and brass, which were already being made during the Chalcolithic period (see Table 33). The most important, however, later became the alloys of iron, known as the ferrous alloys (from the Latin word ferrum, for iron). Since iron ores are one of the most abundant metalliferous ores on the crust of the earth, and its alloys are relatively easy to produce, ferrous alloys have been the most widely used alloys for the last three millennia (see Table 34). 

Iron (chemical symbol Fe, from the Latin name for the metal, ferrum), the most prominent of all the metals in the history of human technology, is a gray base metal that easily combines with oxygen and becomes corroded (Friend 1926). Its importance is most likely due to a number of factors ... 

Metals of the iron family. These metals pertain to the 1st transition row. Iron (Fe, [Ar]3r/64.v2), name from the Anglo-Saxon iron, symbol from the Latin name ferrum (iron). The use of iron dates back to prehistoric times. 

Iron - the atomic number is 26 and the chemical symbol is Fe. The name derives from the Anglo-Saxon iron of unknown origin. The element has been known from prehistoric times. The chemical symbol Fe is derived from the Latin ferrum for firmness . 

ORIGIN OF NAME The name "iron" or "iren" is Anglo-Saxon, and the symbol for iron (Fe) is from ferrum, the Latin word for iron. 

Ferrum purissimum (Merck) yielded, under the same working conditions, initially, 0.4% ammonia, but after a relatively short time this yield decreased to zero. An addition of 1.7% of sodium hydroxide to this pure iron resulted in yields up to 1.8% ammonia, additions of 0.6%... 

The use of iron preparations of the highest obtainable purity (both commercial and laboratory preparations) as starting materials. Principally employed were Ferrum reductum, Kahlbaum, and later, as an ultra pure material Iron Kahlbaum (cost of 1 kg. about 80.00). 

Symbol derived from the Latin name ferrum. 

A particular element is defined by its atomic number - the number of protons in the nucleus (which will equal the number of electrons surrounding the nucleus in a neutral atom). For example, iron is the element of atomic number 25, meaning that every iron atom will have 25 protons in its nucleus. Chemists use a one or two-letter symbol for each element to simplify communication iron is given the symbol Fe, from the old Latin word for iron, ferrum. The sum of the protons plus neutrons found in a nucleus is called the mass number. For some elements only one mass number is found in nature. Fluorine (atomic number 9, mass number 19) is an example of such an element. Other elements are found in nature in more than one mass number. Iron is found as mass number 55 (91.52%), 54 (5.90%), 57 (2.245%), and 58 (0.33%). These different mass numbers of the same element are called isotopes, and vary in the number of neutrons found in the nucleus. Atomic weight refers to the average mass found in nature of all the atoms of a particular element the atomic weight of iron is 55.847. For calculation purposes, these...

Dr. Anbar This is a possibility, at least for ferrum and for copper. In the case of manganese, I am quite skeptical. 

Dr. Anbar In fact, the mechanism you suggested for the formation of hydrogen via the ferrum hydride should evolve hydrogen from this system just as well, with a consequent oxidation of the substrate.
