The Greek mathematician and philosopher Pythagoras (c. 580-c. 500 B.C.) is one of the few figures in ancient times, or indeed in any age, who warrants comparison to the extraordinary Imhotep. Although he is best known for his famous geometrical theorem, his accomplishments ranged far beyond mathematics and involved areas as diverse as music, politics, and religion. Like Imhotep, he was a figure larger than life. Some historians suggest that he never really lived; in fact it appears highly likely…

Notongooglenium Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol). Introduction Notongooglenium Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its placement on the periodic table between Chromium (24) and Manganese (25), it is believed to have a similar atomic and electronic structure to these two elements, and hence similar chemical properties. This means that Chromium or Manganese can be used…

Back on the date of June 18, 1773 Joseph Priestley was in his science lab exploring and studying about the elements. Priestley had done a lot of experiments to find more about the element now known as oxygen. The first experiment dealt with using the previous methods Carl W. Scheele used. Carl W. Scheele was a chemist from sweden, but in his discovery of oxygen he had other people helping him throughout the process. Joseph had thought in his mind, “ If I can do this scientific inquiry on my own,…

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…

What is a camera obscura? What is the principal of optics that makes it work? “A camera obscura, which is literally means ‘darkened room.’ It uses a lens and a sequence of mirrors to project an image of the surrounding landscape onto a viewing surface.” (http://www.scopex.co.za/files/Camera-obscura-ML-1207.pdf) “The principle of optics that makes it work was light travels in a straight line and when some of the rays reflected form a bright subject passes through a small hole in thin material…

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°…

Cobalt: The element Cobalt it is located on the periodic table, Group 9. Cobalt is the 27th element on our Periodic Table. It is a chemical element, it has a density of 8.9 grams per cubic centimeter. Cobalt has a boiling point of 3,100 degrees Celsius (5,600 degrees Fahrenheit). Cobalt’s symbol is Co, The atomic # is 27 so the protons and electrons are 27 as well. Cobalt has an atomic mass of 59 and 32 neutrons. The melting point is 2,719 degrees Fahrenheit. This element was discovered in…

textbook. While his textbook did have a few errors it made important advancements such as defining a chemical element as a substance that cannot be reduced in weight by a chemical reaction. Not only did he make these discoveries and observations but he also assisted in creating the metric…

gases are the group of elements which are like no other elements. The noble gases are the elements grouped as the last group, group 18. These elements, from smallest to greatest atomic mass, are Helium, Neon, Argon, Krypton, Xenon, and Radon. Group 18 wasn't always called the noble gases. this group used to be called the inert gassses. They changed the name of thisi group because they are not always inert, or chemically inactive. the first element in this group is the element Helium.…

Today we might know an atom being the smallest piece of an element that represent an element, but you might not know the whole story. It all being in 1803, when a curious guy, known as John Dalton, who proposed an “atomic theory” with spherical solid atoms based upon measurable properties of mass. Later on Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. John Dalton's research not only changed the face of…
