Atom Egoyan

Carbon's first known use was by the Egyptians and Sumerians in 3750 B.C. It was not until near the end of the eighteenth century was carbon an official element. It was "discovered" by A.L. Lavoisier in France. Carbon can be found in coal deposits, some stars, atmospheres of many planets, meteorites, fossilized remains, and in all living things. Carbon's name originated from the Greek word, "carbo", which means "charcoal" or "coal". The atomic number of carbon is six and the atomic mass is 12

Stainless steel is a product that we see in everyday life, from kitchen appliances to medical tools to constructions materials. But what is the substance that gives it this wondrous stainless characteristic? It is Chromium! 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 the meantime... Some breakthroughs were happening in the world of physics that will soon provide the needed answers. Henri Becquerel was a French Physicist interested in Uranium minerals. Their phosphorescent property was well known. These minerals, after being exposed to sunlight, continue to emit visible light for a period of time. Becquerel interposed a metal between uranium salts and a photographic plate covered with dark paper (to ensure that visible light emitted from the salts won’t interfere)

Particles in Atoms The following section will be describing the atom and all of the particles that make it up. It will start off with what protons, neutrons, and electrons are. This will describe where they are in the atom and what their relative sizes respective one another are. This section will end off with the charges of all of these particles and the total number of all of these particles for every element inside of the carbon family. The entire section will be based off of the particles that

usual positive charge. In 1955, researchers at the Berkeley Bevatron produced an antiproton. • Anti-atoms - Pairing together positrons and antiprotons, scientists at CERN, the European Organization for Nuclear Research, created the first anti-atom. Nine anti-hydrogen atoms were created, each lasting only 40 nanoseconds. As of 1998, CERN researchers were pushing the production of anti-hydrogen atoms to 2,000 per hour. When antimatter comes into contact with normal matter, these equal but opposite particles

Hi I’m Calcium I have 20 protons, 20 electrons, and 20 neutrons. My atomic number is 20 and my atomic mass number is 40. My number of electrons in energy level is 20 and my energy level number is 20. Also the period number I belong in for the periodic table is 4. The discovery name is Humphry Davy and he was the one that made me. The year that I was discovered was 1808 and the country they decided to discover me was in England. My element symbol is Ca. The representative groups and family I

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. Silicon has a lot of uses in our life. If this element did not exist we would not be able to build many houses that are made of bricks and concrete. Silicon is in the form

1898. The name ‘Neon’ comes from the word ‘Neos’ which is Greek for new! The element was found through the study of liquified air, and can be found in the Earths atmosphere. It is found as a gas with molecules. These molecules typically have one neon atom.

As UV and bromine were needed for the conversion reaction to occur, the mechanism must require light as an energy source and the chemical bromine to occur. The proposed mechanism begins with an initiation step of homolytic cleavage of bromine. When the UV light hit the bromine, highly reactive bromine free radicals formed. In the propagation steps, intermediates were formed; a free Br radical attacked the C=C double bond of dimethyl maleate, breaking the pi bond into a single bond, attaching Br to

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
