Informative Speech On Germanium

The existence of Gallium was proposed in 1871 by Russian chemist Dmitri Mendeleev, who named it, based on its position in the periodic table, “eka-aluminum”. He also predicted it’s melting point, density, oxide character and bonding in chloride, that were all similar to the real properties of Gallium.

In order to catch you up am going to tell you about the inventors and how they initiated this project and where their inspiration came from

Helium (Greek helios,"sun"), symbol He, inert, colorless, odorless gas element. In group 18 of the periodic table, helium is one of the noble gases. The atomic number of helium is 2.

I choose Sulfur because of it’s bright yellow color which really catches your attention. I also found it very interesting how much damage sulfur really is to the human. Plus is a very hard element to locate due to the fact that it can mainly be found by hot springs or volcanoes. Sulfur, also spelled sulphur, is a chemical element with the symbol S and atomic number of 16. It is an abundant non-metal and at room temperature is a bright yellow crystalline solid. Chemically, sulfur combines with all elements except for gold, platinum, iridium, nitrogen, tellurium, iodine, and the noble gases. Sulfur forms over 30 solid allotropes, more than any other element. Allotropes are different forms in which an element can exist. I picked this element because

Elements with atomic numbers greater than iron’s atomic number form during the formation of a supernovae, also known as a mini-bang. The process begins when a massive star has depleted its supply of magnesium and silicon, and only has a bare iron ore remaining. Now, the star no longer has the energy to maintain its immense mass against the force of gravity, and as a result, the entire star collapses. This process fuses together electrons and protons in the core, which forms neutrons. After neutrons build up in the ore, the star recoils in the form of an explosion. During the explosion, the neutrons attach to iron atoms in the ore, and begin converting back to protons and electrons. As a result, iron atoms are able to become different elements with greater atomic numbers.

The periodic table is a table that categorises and displays all of the chemical elements. It is made up of groups, periods and blocks. A group (also referred to as a family) are the columns of elements, there are 8 groups. The elements in each family have similar but not identical properties and they all have the same number of outer electrons. E.g. lithium (Li), sodium (Na), potassium (K) are all soft, white, shiny metals because they are all members of group 1. A period is each horizontal row of elements, there are 7 periods. In a period, the elements are not alike in properties, the first element in a period is always an extremely active solid, and the last element in a period is always an inactive gas. Properties change greatly across a given row. Each new period represents the next shell which electrons fill. A block is a region of the periodic, there are 4 blocks: S, D, P and F.

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

According to Silver (n.d.), the characteristics of silver is that it is a soft, white metal that occurs in nature in four forms. The first form is as a native element. The second is as a primary component in silver materials. The third is as a natural alloy with other metals. The fourth is as a trace to minor components in

The rare earth mineral/element yttrium is a soft-silvery, crystalline transition metal, which is naturally found stable in the half-life isotope form of 89Y (1). The element is found on the periodic table in group 3, and period 5, with an atomic number of 39, and can be considered ductile, odorless, lustrous, fairly reactive, and soluble in hot water (1, 2). Not only does this element have a hexagonal crystal structure, it has an atomic mass of 88.906u, has melting point of 1522°C, and a boiling point of 3338 °C(1-3). Yttrium is available in many different compounds, and forms just alone in metal (2, 3). Some of these forms include, but not limited to metal balls, turnings, wire, rocks, ribbon, rings,

Humans hold on. As emotional creatures, we struggle to separate the function of an object from its sentimental value — we see a ragged ribbon from years ago as the sole representation of our sixth grade dance, the poetry project we did in fourth grade as a gateway back to our childhood innocence, and the strip of photos from a trip to the movies just last week already embodies a sense of otherness and warrants preservation. This phenomenon occurs on the societal scale as well, driven from a carnal fear that forgotten history repeats, and communities then strive to create memorials that accurately reflect the lessons learnt, sacrifices made, and complexity of history. As a result, the process of monument-building requires painstaking attention

At Gegadyne every day brings new innovation, but we integrate several products on a regular basis: conveyors, cameras, lasers, robots (of every kind), presses, soldering/welding tools, spindles, indexers, etc. On the controls side, we program all the major PLCs (Fanuc,Siemens etc.) and also computer based systems.

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.

The purpose of this study is to provide some informative information of what it’s like to experience something in life that you have never done before. This experiment allowed me to be able to go somewhere where I never thought that I would ever feel comfortable in going to. I could allow myself some time to be able to walk around, interact, and communicate with those individuals within the inner city of Grand Rapids, Michigan. This place is my hometown and I decided to go to the Southside of Grand Rapids, where the crime rate is high and the individuals who make up the community do not have much. I must admit that at first I was very hesitate about actually going into these poor neighborhoods based on what I saw firsthand on TV, which

As Leonardo DiCaprino said, “As a UN messenger of piece I have travailed all over the world for the last 2 years have seen city’s like Beijing chock by industrial pollution. Accent boreal forests in Canada that have been cleared cut and rain forests in Indonesia that have been incinerated and indimeck farmers whose crops have literally been washed away and America I witnessed the sea level rise, flooding the streets of Miami and in Greenland and the artic I was astonished to see the ancient glaziers are rapidly disappearing well ahead of scientific predictions. All that I have seen and learned on my journey has absolutely terrified me, now think about the shame that each of us will carry when out children and grandchildren look back and realise that we have the means of stopping this devastation but simply lack the political will to do so, yes we have archived the Paris agreement more countries have come together here to sign this agreement today then for any other cause then in the history of human kind and that is the reason for hope.

Firstly, germanium is “hard, lustrous, gray-white, brittle metalloid. It has a diamond like crystalline structure and it is similar in chemical and physical properties to silicon”. Secondly, germanium was discovered by Clemens Winkler in 1886. Clemens winkler named the element germanium in honor of his fatherland. Thirdly, germanium fits in the periodic table since it is non-toxic. Germanium is Group 14 period 4 and is in the Carbon and Silicon Family. In other words, germanium is shiny, hard, soft and is similar to silicon.
