Iron is an important element to the scientific community, especially those involved in the branch of chemistry. Consequently, humans rely on iron for many different things. Iron is diverse from all other elements with regards to its natural occurrence, historic and contemporary uses, the origin of its name, and when, how, where, and by whom it was discovered. It also has unique characteristic physical and chemical properties. Without the discovery, and distinctive properties of iron, life on Earth would never be the same as it is now. Iron occurs naturally throughout the universe in abundance. It is found in places such as stars, including the sun, and is distinguishable in soil and dissolved in groundwater and the ocean in small amounts. It is the fourth most occurring element in the earth’s crust (making up about 5% of the weight), and is also believed to be a main element in the earth’s core. It is found in the Earth’s hydrosphere. Iron is seldom found uncombined in its natural state, with the exception of meteorites, however iron ores and minerals are copious and broadly dispersed. Examples of where its ores are found include white sand, and a crystalline gold-coloured mineral commonly known as fool’s gold. The names of some of iron’s common ores are hematite, limonite, siderite, taconite, magnetite, iron pyrite, chromite, and lodestone. Iron is also found in hemoglobin in the human body to carry oxygen in the blood stream. Overall, iron is a very abundant element in nature that helps to form important factors for life. Iron was introduced throughout the world in what was later deemed the “Iron Age.” The documented approximate date of the beginning of the usage of iron is 1800 BC, though some evidence points to usage as ea... ... middle of paper ... ...ron (Fe).

For example, what are the names of Fe2O3 and FeO. Iron oxide is not an adequate answer; it fails to distinguish between the two possible oxidation states of iron. Is it iron (II) or iron (III). To decide, you must know use the combination of the oxide's fixed oxidation state of 2- with iron's oxidation state required to total for a compound charge of zero. The compound iron(II) oxide, FeO, iron had the oxidation state of 2+ which balances the charge of the oxide ion which is 2-. For the compound iron(III) oxide, Fe2O3, the roman numeral placed after the name of the metal clearly states the charge of each iron atom as 3+. The older system of naming applies either the suffixes —ic for the ion of higher charge and —ous for the ion of lower charge; thus Fe3+ ion can be referred to as ferric and Fe2+ ion as ferrous.
However, free iron can cause significant damage to body tissues, by catalysing the breakdown of hydrogen peroxide to free radical ions such as hydroxyl and hydroperoxyl, which react with cell membranes, proteins and DNA (Andrews, 1999). In order to prevent this from occurring, iron within the body is bound to proteins. These can be divided into three broad categories, haem proteins, iron sulphur proteins and iron containing proteins which do not contain haem or sulphur.
Lithium (Li), the third element on the periodic table, has a soft texture and a silver-white color. This element has an atomic number of three, and is located on the periodic table in the second period of the first group. In addition to being the first alkali metal on the periodic table, lithium is also the lightest metal; its weight is about 6.941 atomic mass units (AMU). Because it is a metal, lithium is mainly used in ionic bonds. Its common compounds include lithium hydride (LiH), lithium nitride (Li3N), lithium carbonate (Li2CO3), lithium hydroxide (LiOH), and lithium fluoride (LiF). Lithium is the thirty-third most abundant element and makes up a very small portion of the Earth’s crust. However, due to its high reactivity, it does not naturally occur in its pure form.
Elements are the basic building blocks of matter due to the fact that they are chemically the simplest substances. Whether we can find them in the air or in our gold/silver necklaces, elements are everywhere! One essential element is hydrogen, the first element on the period table (located under Group 1 as an alkaline metal) is composed of a single proton and electron; therefore having an atomic number and atomic mass of 1 and electron configuration of 1s1. In fact, hydrogen is the lightest, simplest and most commonly found chemical element in the universe (it makes up about 90% of the universe by weight). Interestingly enough, the heavier elements on the periodic table were either made from hydrogen or other elements that were made from hydrogen. The most common isotope formed of hydrogen is protium, with 1 proton and no neutrons. Hydrogen can also exist as both positively or negatively charged. The physical form of hydrogen at room temperature is a colorless and odorless gas. Hydrogen gas is extremely flammable and because of this chemical property, it is used as fuel for the main engine of space shuttles. Hydrogen is an important element and has received a lot of recognition throughout history for its usefulness.
Iron is called a trace mineral, but its effects are mighty. We need it to produce hemoglobin, the oxygen carrier in red blood cells that brings oxygen to the rest of the body. Iron is also needed to produce myoglobin, the oxygen reservoir in the muscle cells.
Earlier in history, from about the time zinc was discovered, or, from the 12th century, zinc was used in many ways. Starting in that same time period, zinc was brought into the industry and was used to improve peoples lives. In 1374 in India, when it was officially recognized as the eighth metal known to man, it was being used for medicinal purposes, such as a cure for sore eyes and healing wounds on the body.

How does the development of steel affect the development of civilizations?Steel is one of the biggest thing why this world is unequal because it was going to make doing jobs easy for everyone. In new guinea, they really couldn't make steel because it was too rainy and they spending all their time getting and making sago.So they didnt have time to have any specialist
Iron comes from the Latin word ferrum. From ferrum its symbol became Fe. The atomic number of iron is 26, and its atomic weight is 55.845. Iron is a magnetic, bendable, shiny white metallic element.
Lead in number 82 on the periodic table. Lead is usually found in ore with silver and copper and it is extracted together with them. Lead occurs naturally in the environment. However, most lead that is found in the environment results from human uses such as lead from batteries, gasoline or lead that has escaped into the environment from places like smelters.
By adding up to 2%,of carbon it makes the steel tough and strong. Although it’s tough and strong, it is able to bend. To make sure that the metal doesn’t rust, it has a zinc coating on it. Iron is 26 on the periodic table,and considered an “transition metal,” meaning that it is ductile and malleable, and conduct electricity and heat. ... “Some other elements that are similar to iron are cobalt and nickel. They are the only elements known to produce a magnetic field.” Zinc is 30 on the periodic table and it is also a transition metal like iron. “The first iron used by humans is likely to have come from meteorites.” A meteorite is a meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel. Meteors are believed to have been from the asteroid belt of Mars and
Aluminum is the most abundant metallic constituent in the crust of the earth; only the nonmetals oxygen and silicon are more abundant. Aluminum is never found as a free metal; commonly as aluminum silicate or as a silicate of aluminum mixed with other metals such as sodium, potassium, iron, calcium, and magnesium. These silicates are not useful ores, for it is chemically difficult, and therefore an expensive process, to extract aluminum from them. bauxite an impure h...
The periodic table, used worldwide by scientists, teachers and students, for quick location of information about elements. The periodic table did not come by overnight though, the periodic table is a table formed from years of work, on the atomic structure. It all started years back with Democritus and his discovery of the atom. This was followed up by John Dalton many years down the track, after elements had been discovered Dalton attempted to create a way to make the elements easier to remember. 84 years later, JJ Thomson discovered electrons, which were key to the periodic table, and in 1889, Dmitri Mendeleev invented the periodic table. Years later Henry Moseley worked out how to measure atomic numbers of elements, and just 9 years after Neil Bohr explained the structure of the atom which further explained why Mendeleev had placed each element in a specific row or column. Finally James Chadwick discovered the neutron in 1922.
The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed.
