Research Paper On Gallium

For our science assessment we had the task to research about a metal of our choice. Since I am really into computers, I chose copper. A metal used in all kinds of wires, cpu’s and other stuff without a computer wouldn’t work. This fits really well into what we have to do for the second part, describe how this metal has helped human society.

Mercury is a heavy metal with serious side effects like heart problems, digestive imbalance, loss of memory, breathing problems, ADD, depression, etc.

In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

There are few people who don’t know what Deaf President Now (DPN) is. DPN was the result of Gallaudet’s newest president being a hearing woman, in 1988. After a week, I. King Jordan was named Gallaudet’s first deaf president. He remained president until 2006. Robert R. Davila succeeded him.

George Gallup was born in the fall of the year 1901 on November 18, in the small town of Jefferson, Iowa the heartland of America. He grew up in an octagonal house build by his father, who was also named George. His father, George Henry Gallup, a farmer as well as a real estate dealer in agricultural land. From a young a George Jr. was already being to have a sense of democracy based on the sturdy, self-sufficient farmer. As a teenager, Gallup Jr. worked as the manager of dairy farm and used his salary to start a newspaper at his high school. He enrolled in the University of Iowa in 1918, played football and became the editor of the Daily Iowan as he began working for three U of I degrees, he received a bachelor's degree in 1923, a master's in 1925, and a doctorate in 1928.

While liquid gold may be a modern allegory for something desirable, there is another liquid metal that is quite the opposite of desirable. Mercury is an unusual metal in that in its standard elemental form it is a liquid. Due to the increase in industry over the last 100 years, Mercury levels have risen, which cause serious damage to humans.

In 1817, a man named Thomas Hopkins Gallaudet, was a graduate from Yale University and lived in Hartford Conneticut. He met Alice, the daughter of his neighbor, Mason Cogswell, a well known doctor of the area. He found out that Alice was deaf and decided to teach her on how to read and write some basic things. He did really good in helping her and was encouraged by Cogswell to establish a school made for deaf people to learn on how to communicate. With enough help and funds, Cogswell and some others were able to send Gallaudet out to Great Britain where there he can the ways of deaf communication. When he got there he first was going to learn about an “oral method” of instruction at the Braidwood Schools in Scotland. This method was strongly

Mercury also came up in science class. When first presented with the jumble of the periodic table, I scanned for mercury and couldn’t find it. It is there—between gold, which is also dense and soft, and thallium, which is also poisonous. But

10. Your friend says that what makes one element distinct from another is the number of electrons about the atomic nucleus. Do you agree wholeheartedly, partially, or not at all? Explain.

Gallaudet get ready to move back to the united states with Laurent Clerc. In 1817, Gallaudet established the nation’s first free public school for the deaf school name was "the American Asylum or Connecticut Asylum" and later become name "American School for the Deaf or ASD".The first sign language teacher in the school and in The United States was Laurent Clerc, teach French Sign Language (LSF).

There are characteristics of Mercury that make it an appropriate target, and some that make it not. The different characteristics presented in the case are as follows:

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.

Noble Gas is located in far right column of periodic table and is known for having full valence electron shell. Helium, Neon, Argon, Krypton, Xenon, and Radon are known Noble gases in the periodic table. All of those elements are odorless, colorless in standard condition. Ununoctium is the only synthetic element of Noble Gases. The name Noble Gas came from the translation from German noun Edelgas which implied that it is chemically very inert. Because Noble Gas elements have 8 valence electron and stable without any formation of compound, its first ionization energy is highest out of all the groups in periodic table.

Germanium weighs 72.61lbs, and the boiling point is 2830 degree Celsius. In addition, germanium has 9 isotopes, and the atomic mass i 72.59. However, “the element germanium is both metals and nonmetals. To be more precise, germanium is a very important element that light and shiny.

The people with the most risk of damage by mercury are unborn fetuses and children. Studies seem to show that the metal
