Titanium is a strong, light metal. It is as strong as steel and twice as strong as aluminum, but is 45% lighter than steel and only 60% heavier than aluminum. Titanium is not easily corroded by seawater and is one of the elements in the periodic table discovered by the British chemist, Reverend William Gregor in 1791, in Cornwall, Great Britain. Titanium was originally named Gregorite after William Gregor. As he was mining one day he found a residue he couldn't identify and thought it might be a new metal. In 1795 Martin Klaproth an Austrian chemist, verified that Gregor had in fact discovered a new element. Klaproth named the element "titanium", after the Titans from Greek mythology. In 1910, American professor, Matthew Hunter was the first to make pure titanium. (Titanium Industries, Inc. 2016). Titanium didn't begin …show more content…
It makes up 0.57% of the earth's crust. Titanium is not found freely in nature but is found in minerals such as rutile (titanium oxide), ilmenite (iron titanium oxide) and sphene (titanite or calcium titanium silicate), (Royal Society of Chemistry, 2016). The abundance of Titanium in the universe is 0.003%, (Wolfram Research, Inc). Common Compounds that Titanium makes are are with Hydrides, Fluorides, Chlorides, Bromides, Iodides, Sulfides, Selenides, Tellurides, Nitrides, Carbonyls, and Complexes.

It was discovered by the British chemist, Reverend William Gregor in 1791, in Cornwall, Great Britain. Titanium was originally named Gregorite after William. Pure Titanium was first produced by American professor Matthew Hunt. It was first produced to make military equipment and spacecrafts. Titanium is mostly used for a pigment in white paint. It is the 9th most abundant element in the earth and it makes about 0.003% of the
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
When and how the element was discovered including who discovered it and the circumstances and/or investigations that lead to them discovering the element?
Strontium was discovered by Adair Crawford, an Irish chemist, in 1790 while studying the mineral witherite (BaCO3). When he mixed witherite with hydrochloric acid (HCl), he did not get the results he expected. He assumed that his sample of witherite was contaminated with an unknown mineral, a mineral he named strontianite (SrCO3). Strontium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of a mixture of strontium chloride (SrCl2) and mercuric oxide (HgO). Strontium reacts vigorously with water and quickly tarnishes in air, so it must be stored out of contact with air and water. Due to its extreme reactivity to air, this element always naturally occurs combined with other elements and compounds. Strontium is very
...stainless steel and Co-Cr alloys which results in poor rigidity. Alongside this, titanium is a light material which would make it difficult to see under x-ray imaging (Hanawa, 2009).
Holmium is a chemical element and is the sixty seventh element on the periodic table. It is located in Period six and it is a member of the lanthanide group. It was discovered in 1879 by a Swedish chemist named Per Theodor Cleve. Like Carl Gustaf Monsander who discovered the elements lanthanum, erbium and terbium Theodor also used similar strategy's to find contaminants in the oxides of uncommon earth elements. He first looked at the oxide of erbium and was able to split it into two types of materials one being brown and the other green. This in turn caused Theodor to find the oxide of holmium (it was the brown material which is known as holmia) and this was how the element holmium was discovered.
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 Beryllium element, an alkaline earth metal which belongs to group II of the periodic table, was first discovered in 1798 by L.M. Vauquelin. Vauquelin,a French chemist, was doing work with aluminum and noticed a white powder that was nothing like that of aluminum or any of its derivatives. Vauquelin named this mystery powder, gluinium because of its sweet taste was like that of glucose. In 1828, Wohler, a German metallurgist reduced it to its metallic form and renamed it beryllium.(figure 2)
Two chemists came upon the discovery and those two are: Sir William Ramsay, who is from Scotland, and Morris M. Travers who is from our homeland. This element was founded on May 30, 1898. The way that those two came upon the element Krypton was that they first found the elements Argon and Helium. From using their common knowledge they figured that there had to be some elements between those two on the periodic table, so they did a ton of experiments and through trials and trials they came up with a couple more elements and one of those elements was Krypton. Next the essay will discuss the shape of Krypton and where it is found.
The slave witch from South America. Tituba of Salem and her family were brought from Barbados to the United States. Tituba was captured at a young age and bought by Samuel Perris which later was brought to Boston Massachusetts in the late 1600’s. She became a servant for Samuel Perris and his family. “In November of 1689, Samuel Parris moved Tituba and his family to Salem after he was appointed the new minister of Salem Village” (Rebecca Beatrice Brooks, Tituba The Witch of Salem). People used to confuse Tituba with half Indian American and African, but the truth is that her race was unknown. No one knew where was she original from since she was captured and brought to Barbados then moved to Boston when she was later sold as a slave.

In this small quaint town on a sunny yet cold afternoon, I sat in and observed this dwelling for several minutes. Watching numerous people walk in and out of this dwelling. Some carried objects in but came out empty handed, while others walked in emptied handed and came out with different sized items. This dwelling is square in shape built in brick, quite large in capacity with double doors, a parking lot with twenty or so spaces for vehicles, and a large metal shape blue object in the parking area. There are also a few square shaped objects on wheels that are being operated by two males. These men carried large plastic bins filled to the brim and placed in the back end of the metal object.
Mr. Cronstedt discovered nickel in a mineral called niccolite. He originally planned to extract copper from this new mineral but got none at all. This is why nickel, at first, was called "false copper". Instead, Cronstedt got a silvery-white metal, which was eventually used for other things.
It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis of chloride or hydroxide.
Klemm and Bonner made the first metal by heating ytterbium chloride and potassium in 1937, and in 1953, Daane, Dennison, and Spedding produced pure metal. Since then, it has been utilized in alloys and with stainless steel to improve grain purification and strength, as catalysts in organic chemistry, in portable x-rays that need no electricity (Yb 160), in stress gauges to monitor ground formations during earthquakes/underground explosions, and as a fiber laser amplifier in marking and engraving. Yet possibly its most important use to date, is its “future redefinition of the SI second” based on the development of a new atomic clock utilizing ytterbium, the optical lattice clock (Physics/General Physics, 2013).
Dalton was the first person to develop a scientific atom theory, the ancient Greeks had ideas about the atom but could not prove it scientifically. Antoine Lavoisier and Dalton are responsible for the discovery of 90 natural elements. Dalton also explained the variations of water vapor in the atmosphere, the basis of meteorology. Dalton’s atomic theory says that each element contains its own number of atoms. Each element has its own size and weight.
