How Lanthanum Play A Role Within My Everyday Life

In 1781, Carl Wilhelm Scheele discovered Tungsten, which is also known as Wolfram. The word Tungsten is used in the United States, but Wolfram is still used in some European countries. Tungsten comes from the Swedish language which means “heavy stone”. Tungsten is a very strong, shiny, gray-white metal that makes up just a tiny fraction of the earth’s crust and is always combined with other elements as compounds. Every tungsten atom has 74 positively charged protons in the nucleus which means it also has 74 negatively charged electrons revolving around the nucleus. Tungsten played a big role in the background of World War II. Portugal was the main source of this element which meant, they were put under pressure by both sides because of

Recently, Thomas Graedel, from Yale university stated that for metals like yttrium, including the metal itself, it seems inadequate, and nearly unknown that there are any alternatives that can match the element’s effectiveness, and be more greener(9). Surely, many can assume that other rare earth metals, including the family lanthanides can easily be alternatives for yttrium, but because of most be either more reactive, less effective, and even rarer to obtain/ extract, these metals cannot be alternatives(5,9). Moreover, Mr.Graedel, and other sources stated that the world needs to work on creating technology, and day-to-day items without the use of these metals, as it would be much more greener(9), and prevent further over-exploitation of the resource. Despite the fact, the yttrium is a great “greener” alternative for other elements/chemicals such as replacing lead in automobiles, or even replacing elements in medical needles (5,9)

n the year of 1879,Swedish chemist Lars Fredrik Nilson discovered an element called Scandium.Scandium was found in Uppsala,Sweden.Nilson was studying the rare earth metals and tried to divide the element ytterbium with using euxenite and gadolinite.A part of his method needed the preparation materials which reacted to form erbium nitrate.Nilson added heat to the nitrate and found that his sample had small quantities of a element no one has ever heard of with a low atomic weight.That unknown element soon became Scandium!Soon after his discovery,Nilson started studying the element and determined that Scandium’s atomic weight is about 44.In the year of 1937,Metallic Scandium was first prepared by Fischer and his collegaues.They performed electrolysis

A few metal elements in high temperatures may enter an excited state and they’re seen by emitting a light of color. Comparing the substance flame with the flames of the reference table will help identify the element of the unknown metal. First we placed each of the liquefied metals in flames and observing their color changes by collecting data. Lastly, observing the color of the liquefied metal, placing it in the flame with a wire loop could emit a color change and this concludes the experiment. The unknown metal was exactly the metal ion that was hypothesized. The unknown metal

Tungsten, formerly Wolfram or Wolframite, is not naturally found in nature, and can only be created by taking either protons or neutrons from naturally occurring substances. In the sixteenth century, German smelters discovered it as an accompanying mineral to tin ores. When trying to smelt these ores, they sometimes found foam like deposits would form, consuming the tin ores they found valuable. Due to this phenomenon, it was said that it “Tears away the tin and devours it like a wolf devours sheep.” and labeled somewhat of a nuisance material. The name wolfram was also due to the substances black color and its hairy appearance. A century and a half later it would be given the name Tungsten after another tungsten ore called

Before history was recorded humans had knowledge of certain elements including gold (Au), copper (Cu), silver (Ag), mercury (Hg), tin (Sn) and lead (Pb). Nevertheless, it wasn’t until the year of 1669 that Hennig Brand discovered the very first element – Phosphorous (P) – through scientific inquiry. Hennig Brand discovered phosphorous through extracting it from urine. Due to the element having the ability to grow in the dark it was referred to as “light bearer”. In 1980 English chemist Robert Boyle discovered phosphorous independently, following Hennig Brand keeping the process of his discovery secret.

Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten, which directly translates to heavy stone. Its name in Swedish is volfram, however, in order to distinguish it from scheelite, which in Swedish is alternatively named tungsten.

Arsenic has an atomic number of 33 and a relative atomic mass of 74.922amu. Arsenic is an odd element, as it acts like metal even though it is a natural element. Arsenic is found in natural environments, and in limited quantities found in rocks, soil, water and more. Arsenic was very known to the ancient Egyptians and the Chinese, they used Arsenic as a way of gilding metals. The orpiment(As2S3) and the realgar (As4S4) : are the two Arsenic sulphide minerals that Greek Philosopher, Theophrastus. As2O3 is the trioxide, is one of the end products of copper refining. This is a form of arsenic that has also been known for awhile now, and it is called white arsenic. The official discovery of arsenic is to Alberts Magnus in around the 1200s. As to the physical property, it is radiant, has a silver colour and fragile, as it is a semi-metal. When in exposed to air, it is rapidly damaged, because of the usual elements in air, such as nitrogen and more. Arsenic is not particularly used in any technology, but recently we use Arsenic in semiconductor gallium arsenide, it can convert electric currents to laser lights. Usually it is not used

Thallium is a metal located in family 13 and period 6. Ti represents the atomic symbol for Thallium. It’s atomic number is 81, while it’s atomic mass is 204.38 or just 204. There are 81 protons and electrons and 124 neutrons. 5 energy levels can be found in this element; they consist of 2 in the first, 8 in the second, 18 in the third, 32 in the fourth, and 3 in the fifth. Due to the last energy level having 3 electrons, that would also the the number of valence electrons it has. This element was founded by Sir William Crooke in 1861. In 1862, his Crooke and a French chemist Claude-Auguste Lamy concluded thallium to be metal isolating it.

It also is a alkali metal and has a relatively low melting point which is 28.5 C. Cesium can be found in some types of food and some types of water and is radioactive. Its rare that people can have health risks from just Cesium itself, but when combined with radioactive Cesium which isn’t common it can be very harmful. If those two combine people could experience cell damage caused by radiation from the Cesium particles. Symptoms such as Bleeding, nausea, vomiting, and diarrhea can all happen, and if you're exposed to it long enough you may have a como or even

The Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures.

Tungsten is a chemical element with atomic number 74 and symbol of W. The word tungsten comes from the language Swedish which means heavy stone. This is a rare, hard metal under normal conditions when it’s uncombined. Tungsten is found naturally on Earth only in chemical compounds.
