Location of Titanium on the Periodic Table: http://bit.ly/1TiYE0o Discovery of Titanium Titanium was first discovered by a Reverend with the name of William Gregor in the United Kingdom (he was an English pastor at the time) in 1791. Except, it wasn't until 1910 when a man by the name of Matthew A. Hunter an American metallurgist was the first to have produced pure Titanium. A plaque was later made
In a Chinese ritual, tubes made of bamboo filled with gunpowder were thrown into a fire for explosions. After this, gunpowder and tubes have been used for celebrations. As rockets became more advanced, these “fireworks” became more advanced, with more shapes and sizes.
Shivering, the children are muffled in their warm, cosy hats and and gloves. Their gloves grasped the, close as the gathering, anticipitave crowd waited impatiently for the exuberant firework display to begin. The damp, slippery grass was blanketed with empty crisp packed, broken plastic cups and used sparklers. The air was flooded with the unhealthy smell of greasy hot dogs and beef burgers enticing anyone who smelt it. The muttering and voices of the crowd dominated everyone's ear drums. Eventually, the crowd went into silence. The crackle and pop meant only one thing. The fireworks had begun. The crowd watched in utter fascination at the man made shooting stars revealing elegantly in the twilight sky. The glow was illuminating the night
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
How can one human mind organize and memorize over 100 elements? In 1869, Dmitri Mendeleev, a Russian chemist and inventor, was credited with creating and publishing the Periodic table. The Periodic table is an arrangement of the chemical elements discovered on earth. These elements are organized by their atomic number
The year is 1776. July 3, 1776. One day before a new country was born, the United States of America. The former colony of Great Britain has just finished it’s Declaration of Independence, and signing of the document by revolution leaders is planned for the next day. John Adams, a

Strontium is a chemical element with symbol Sr and atomic number (protons in nucleus) 38 and atomic weight 88.1 It is a soft, silver-gray metal, and has physical and chemical properties like to Calcium and Barium. It is available as four stable isotopes ubiquitously (Isotopes are differ in forms of an by number of protons in nucleus but possess a variable number of neutrons.) Strontium-88 is the most dominant among other forms, comprising 83% of natural strontium, where in additional three stable isotopes and their relative abundance are strontium-84 (0.6%), strontium-86 (9.9%), and strontium-87 (7.0%). Strontium is available ubiquitous vitally as as celestite (SrSO4) and strontianite (SrCO3), and it comprises about 0.025% of the earth’s crust. There are 16 major radioactive isotopes of strontium, but only strontium-90 has a half-life sufficiently long (29 years). In comparison with half-lives of remaining strontium radionuclides are fewer than 65 days. Strontium-90 decays to yttrium-90 by decaying a beta particle, and yttrium-90 decays by decaying a energetic beta particle with a half-life of 64 hours to zirconium-90. The key health concerns for strontium-90 are associated to the energetic beta particle from yttrium-90.2
Discoveries on the 1800s such as Thorium being discovered by an amateur mineralogist, Morten Freeman 2 Thrane Esmark and identified by a Swedish chemist, Jӧns Jacob Berzelius in 1828. Thorium was
After we created the firework masterpieces, I tried to explain to my son that we would see lots of fireworks over the weekend. I told him they would make loud “kaboom” sounds and have so many pretty colors, just like his paintings. He was so happy about the idea but still confused at the same time so I showed him a few videos on Youtube. His face lit up when he saw the fireworks bursting along to music in the videos. He would look wide-eyed at the video & then point to his paintings while shouting “Fah-wurk! Fah-wurk!”. Hopefully this will be a nice introduction to this holiday's loud spectacle. Last year he was too small to understand or even be afraid of the explosive sounds. This year I’m hoping he enjoys the beauty and excitement of the fireworks like I did as a young boy and still do to this
There are many different fourth of July celebrations throughout Gaston County. This summer, I celebrated the fourth of July in Ranlo, observing fireworks the small town presented. There was food and beverage sales before the fireworks as well as music to get the community pumped and to promote the
Growing up in America I get to experience fireworks every Fourth of July, which is always a highlight of summer vacation. There is no better way to celebrate freedom and our pride for our country than to display it with fireworks. So every Fourth of July almost every city in America participates in this ritual. My hometown is one of the many places that puts on our own fireworks display for the whole city to see. And my friend just so happens to live directly across from the area where the fireworks a shot of from. So we have the perfect place to see the show. Exactly at nine o'clock we gather in the front yard with blankets and chairs waiting with as much patience as we can. Everyone from the old to the young are excited to see the beautiful
The banging in the sky,the shouts of thousands of people, and the bright, dazzling lights make everyone gaze at the sky. Fireworks and more specifically their components are present in the cosmos, have enabled evolution, and have fine tuned our cultures. Fireworks are very versatile for any culture no matter the uses. Also fireworks have made an enormous impact on our history, ever since they were created in China. Fireworks are extremely impressive and can be used in several ways.
While working on her dissertation she became fascinated by the work from Henri Becquerel. Becquerel’s discovery of uranium salts emitting rays inspired her to conduct further research. Within a couple months of beginning her research she made two important discoveries that “led her to formulate the theory that the rays were the result of something happening within the atom itself, a property she called radioactivity” (Goldsmith). She discovered that the rays were emitted from the anatomical structure of the atom and the outcome was not due to the interaction of molecules. Pierre Currie later abandoned his own research in crystals to help his wife in testing minerals that revealed high levels of radioactivity. From Marie Curie’s testing she concluded that a new more powerful element was responsible for the high levels of radioactivity. The Curies confined their research to the mineral pitchblende because it emitted the strongest rays. They then diligently and progressively separated pitchblende by chemical analysis. They measured the radioactivity of the separate components. “In July, 1898, she and Pierre successfully extracted an element from this ore that was even more radioactive than uranium; they called it polonium in honor of Marie’s homeland” (Goldsmith). Within that same years they identified a more radioactive element. This element which was embedded in the pitchblende was named radium. To prove their discovery they needed to isolate a pure form of this element. Which was no easy task, considering that these elements were extremely small and almost unnoticeable. In 1902 they were able to isolate enough radium to confirm its existence. Marie Curie then received a doctorate degree from the Sorbonne University, making it the first awarded to a women in Europe. In 1903 Pierre and Marie Curie and Henri Becquerel where jointly awarded the Nobel Prize in physics for their
When we see fireworks explode, what we’re actually seeing is the explosion of components inside the aerial shell. The aerial shell is made up of gunpowder and stars, small lumps that are comprised of fuel, an oxidizing agent, a metal-containing colorant, and a binder. These stars are what give the fireworks their colors. (De Antonis, pg 8). The metal-containing colorant produces the color when it’s exposed to a flame (in this case, the ignition of the gunpowder) then the fuel and oxidizing agent combine to create a chemical reaction that yields powerful heat and gas (De Antonis, pg 8).The binder holds all these ingredients together when the firework explodes. When the fuse at the bottom of a firework is lit, the energy propels it upwards until
