Beryllium General Characteristics According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to…
Magnesium Alloy: Microstructure Characteristics: Fig (8) : Shows the microstructure of Magnesium alloy. Picture source: http://www.omicsonline.org/JMSTimages/2155-9589-2-114-g001.html Magnesium alloys have a hexagonal lattice structure. They are the lightest of all structural metals. Magnesium alloys possess a low galling tendency as a bearing surface in conjunction with shaft hardness above 400…
Our prior knowledge and mindset can define the way we approach new knowledge and experiences; we see what we believe, each letting our schemas have an affect on the conclusions that we draw from situations. Our perception of what occurs and the way we go about our motives are based off of a previous inclination or concept towards the situation we are preparing to encounter. This schema is useful in helping us organize and interpret information based off of our previous experiences or lessons,…
first periodic table in 1869. The periodic table he made was very different from the modern day periodic table we know today. Henry Moseley updated Mendeleev's version of the periodic table in 1915. This is more like the periodic table that we know and use today. The only difference is that there has been many more elements added. Mendeleeve also had predicted a lot of the characteristics and properties of elements that would fill up some of the spaces that he left in his periodic table.…
radioactivity is now frequently used to treat cancer and has the potential to save lives. Marie Currie was a powerful figure who benefitted society’s view of women through her winning of two Nobel Prizes, discovering radioactivity and two periodic table elements, and founding…
Before talking about the elements, the atom must be discussed first. Atoms are the building blocks of everything—from the structures of a building to a household pet. The idea of the atom was first suggested by Democritus, a Greek philosopher born in 460 BC. Democritus hypothesized “that atoms were indivisible and infinite in size and shape as well as firm and completely solid” and that they “existed in a void moving about combining and recombining” (European Graduate School). Later on, a…
The Periodic table is a table that organizes the different known elements, and Neon is one of those elements. Neon is an element that is a non-metal and also a noble gas. The start of the element, Neon, was when a Scottish chemist named William Ramsay discovered Neon, Krypton, and Argon, which are all noble gasses ("Periodic Table of Elements: Los Alamos National Laboratory." Periodic Table of Elements: Los Alamos National Laboratory). For this achievement, William Ramsay won the Nobel Prize in…
Bromine was discovered in 1826 by a French chemist by the name of Antoine-Jérôme Balard. It contains a molar mass of 79.904 grams per mole (g/mol). Bromine falls within group 7 of the periodic table and is a halogen. Its atomic number is 35 and is one of seven diatomic elements. Bromine is one of two elements that holds the natural state of liquid. I chose bromine for my independent paper because of many other elements I knew little to none about, I have never heard of bromine and was…
The element Titanium is a very light metal and it’s in the periodic table group 4. This element is a transition metal and the symbol is Ti. The color of titanium is a silver grey and white color. The atomic mass is 47.867 and atomic number is 22. This element however is resistant to chlorine, and sea water. It has 22 electrons, 22 protons, and 26 neutrons. The density is 4.54 The discoverer who found titanium is William Gregor a Mineralogist. The year it was discovered was in 1791. Where it had…
The element Magnesium got its name when it was discovered. It is a silvery white metal that is highly reactive. Its chemical symbol is Mg and atomic number is 12. Its atomic mass is relatively 24. Therefore, it has 12 protons, 12 neutrons, and 12 electrons. According to Steve Gagnon in “The Element Magnesium” Magnesium was isolated by Sir Humphry Davy, an English chemist, through the electrolysis of a mixture of magnesium oxide and mercuric oxide in 1808. Magnesium has a melting point of 650°…
