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).

Aluminum is the third most abundant element and most abundant metal in the Earth’s crust. Aluminum is never found in the free element state in nature. It
Iron is naturally iron oxide and purified iron rapidly returns to a similar state when exposed to air and water. This whole process can be seen below in figure 3 – ‘The corrosion
Just as the title of the chapter suggests, the main focus of Chapter 11 is how elements found on the Periodic Table are not always what they appear. Kean begins this chapter with describing how elements can be unpredictable in some conditions, and uses example from the past to...
Iron is a trace element, which is a group of minerals present in small quantities in the body. Other trace elements include copper, zinc, selenium, manganese and iodine. These minerals cannot be synthesized by the body and must therefore be supplied in the diet. Iron is the most common trace element in the human body; adult males have approximately 3.5 g iron in total, or 50 mg per kg body weight while females have about 2g total iron or 35 mg per kg bodyweight. Iron can exist in oxidation states from -2 to +6, but mainly exists in the ferrous (+2) and ferric (+3) states in biological systems. As iron has the ability to accept and donate electrons readily, it can interconvert between these two forms with ease. Thus, iron can participate in
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.

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.
magnesium, silicon, and sulfur. Eventually, silicon and sulfur ignite in the star's core to form iron and nickel. (Hansen, 1994)

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.
It has a lot of alloys. One of its alloys is bronze. Bronze is almost exclusively made from copper. Another alloy is nickel. Copper is in some of the pesticides and other poisons that we people own. The amount of copper that goes into these poisons is a small amount. It can as small as a molecule the has copper in it that goes into the poisons. Copper pipes are used to carry water into houses. Copper can conduct electricity, so it is used in a lot of
This book was given to me by a good friend who knew that I had an interest in Asia. I chose to read it because it was a true story and was told that it was a good read.
The iron hypothesis, created by John Martin, states that if the ocean could be enriched with iron, more phytoplankton blooms could grow that would take the carbon dioxide out of the atmosphere and possibly reverse the greenhouse effect. Martin’s test demonstrated that when you germinate high-nutrient, low-chlorophyll zones in the ocean with iron, you increase the production of phytoplankton blooms, this information proves his hypothesis true. This will improve the earth by making the carbon dioxide return to its natural level in the atmosphere. From that, the ice caps would not melt and animals would not go extinct. If the ice caps do melt, then there would be a worldly flood and the salt water would infect the clean water that we need to live. John Martin’s hypothesis could save the livelihood of humans and animals.
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
