Germanium Research Paper

Rare earth metals are a series of chemical elements that are found in the earths crust (Rare Earth Tech. Alliace), and, because of their unique are used in a variety of different technologies, including computers, mobile phones, transport (cars, motorbikes, buses) and for defence purposes (Rare Earth Tech. Alliace). The unique properties of rare earth elements reduce size, weight, increase efficiency and stability, as well as reducing emissions and energy consumption. There are 17 main elements that are called rare earths, 15 from the lanthanide series, and two more that have very similar properties

As previously stated, mercury is number 80 on the periodic table of elements. It is a metal, a transition metal to be exact. It has a symbol of “Hg”, an atomic mass of 200.59, and there are 7 known stable isotopes

Mercury, (its chemical symbol Hg), comes from the Greek word hydrargyrum, meaning, water silver, although T is commonly named as quick silver. Mercuries atom number is 80 and its mass number is 200.59. It is the only metal that is a liquid at room temperature (around 20-25 degrees Celsius).

The element mercury was known to ancient Egypt and China. They used it thinking it would prolong their life. It is one of the metal which is liquid in normal pressure and temperature. Which helps us to understand many parameters which are dependent on pressure and temperature. It was recognized as an element by A. L. Lavoisier in the 18th century. Some of the properties of the element are as follows.

Gallium has properties similar to Mercury and water. Water expands as it solidifies, so does Gallium. Mercury is a liquid at room temperature, so is Gallium. Gallium is in Group 13 and Period 4 on the periodic table. Gallium also has a properties of sticking to glass, creating a mirror-like substance. Something else I should mention is that the hotter Gallium

Gallium is the element number 31. Gallium is the one of the only metal that will be liquid in your hand. Mercury is an liquid metal element number 80 that freezes at -280 degrees fairenheight with liquid nitrogen. Mercury was a popular thing to play with but people realized that they were slowly being poisoned by it.Gallium is not known to be toxic, but it can stain your hand dark brown. cesium is another metal that will literally melt in your hand but without putting it in an ampoule, it will explode and catch on fire. Gallium tends to be the less dangerous type of liquid metal other than explosive cesium to lethal mercury. Gallium melts at a temperatue of 83.4 fairenheight. In order to buy gallium you must first order it then, they must purize

The boiling point is a temperature of 5,131 degrees Fahrenheit. Its state of matter at 20 degrees Celsius is a solid. That’s about it with the numbers but I don’t promise there won’t be any more.It has quite a bit of chemical properties. A couple are is when its pure germanium is a hard, lustrous gray-white, brittle metalloid. It has diamond-like crystalline structure and it is similar in chemical and physical properties to silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid. When it is near fire or on it nothing happens and it stays a solid unless you get it to 1,721 degrees Fahrenheit and it will start to melt. Then if you get it to 5,131 degrees Fahrenheit it will start to boil. This element is used in the semiconductor industry. They also use it in electronics such as cell phones, tablets and other things. They use it to create alloys and as a phosphor in fluorescent lamps. Its value in the world is 3 dollars a gram. It has a good importance to living organisms. It appears to aid in proper immune system functioning, it also may help the human body detoxify toxins, may treat food allergies, and may promote wound

Cadmium is a natural member like zinc and mercury. Cadmium belongs to group 12 of the Periodic Table of the Elements. Cadmium is classified as a soft, ductile, silver-white or bluish white metal. Cadmium is found in association with zinc sulfide based ores. It can also be found in sedimentary rocks at higher levels. Cadmium can be found throughout the environment within the natural resources. Cadmium weights 8.64 g/cm3 at room temperature. The atomic number for cadmium is 48. Atomic weight is 112.1 (Cadmium.org).

Silicon is a solid in group 14, period 3. Geranium is another solid right under silicon in the periodic table. These two elements are examples of metalloids. Metalloids are elements that are intermediate to metals and solid nonmetals. Silicon and germanium have many uses in our life that give us a lot of things we all have now.

(20) Metals are classified variously—according to molecular weight (“heavy metals”), according to chemical properties (periodic table), according to toxicology. Please do the

In 1875, Paul-Emile Lecoq de Boisbaudran has discovered an element, Gallium. This element had been discovered in the country of France. Gallium is also known as “Ga” on the periodic table.

Chromium is a transition metal in period number 4 and group number 6 under the symbol Cr and atomic number 24 on the periodic table. It has an atomic weight of 51.9961 rounding to 52, melting point of 2180K and boiling point of 2944K. It was discovered by Louis-Nicholas Vauquelin in 1797.

Chromium is part of the periodic table this element has the atomic number of 24 which means that it has 24 protons and 24 electrons. Its atomic mass is 51.996, but when reduced it will be 52. The density of the element is 7.19, and the temperature for it is 20 Celsius. And the melting point of the element is going to be 1907 Celsius. This information gives you the idea of what my element has.

My element is Boron. Boron compounds such as borax have been known and used by ancient cultures for thousands of years. Boron was first partially isolated in 1808 by French chemists Joseph L. Gay-Lussac and L. J. Thénard and independently by Sir Humphry Davy in London. Davy first tried to produce Boron by electrolysis of boric acid, but was not satisfied with how the results turned out. In 1909, American chemist Ezekiel Weintraub was able to produce 99% pure Boron, by reducing Boron halides with hydrogen. In 2004, Jiuhua Chen and Vladimir L. Solozhenko produced a new form of Boron, but were not certain of its structure. Boron is a tough element, very hard, and very resistant to heat. In its crystalline form, it is the second hardest element of all the

I chose the element Silver (Ag) from the periodic table as my favorite because it’s a beautiful piece of metal. Its my favorite element because, it’s commonly used for jewelry and looks very cool on me when I wear a silver necklace. Also, because its color is just very appealing.
