crown ring made out of. What is interesting about this topic is that there is a lot of ways to study the gold crown ring. For example, you can test the mass, volume, and density of the ring. In the periodic table Au is the symbol for Gold, it’s atomic number is 79. The Properties of Matter are Mass, Weight, Volume, and Length. Each property has its own way of working with different types of things. It is believed that the material of the crown in this study is fake gold because gold has the…

The element name given is Phosphorus, it is symbolized in on the periodic table as a P. Its atomic number is 15 and the atomic mass is 30.974 (which is a rounded number). Group number the element is apart of on the periodic table is 15. Phosphorus’ listed isotopes are P-31 (stable) and 23 others and its electron configuration is [Ne]3s2 3p2. Physical properties of the element are varied depending on which allotrope of the element you are talking about. White Phosphorus has a melting point of…

My chemical element is Sulfur. If you were to be looking at a periodic table, its symbol would be S. Sulfur’s atomic number is 16. Sulfur has 16 protons, 16 electrons, and 16 neutrons. Sulfur’s atomic mass is 32.065 and its mass number is 32. Sulfur comes from the Sanskrit word “Sulvere” and also the latin word “Sulphurium”. Sulfur was discovered in Ancient times and has been mentioned in both the Bible and the Torah. Sulfur is commonly found in meteorites, volcanoes, hot springs, and as…

contains patterns and organization. A conceivable structure like the cube allowed for easy application of Lewis’ atomic postulates. Lewis’ model explained his six postulates about the chemical behaviors of an atom. The first postulate is that an atom has an essential kernel that does not change in chemical reactions and “possesses an excess of positive charges corresponding to the ordinal number of the group” in which the…

Elements above the atomic number 95 are produced in a particle accelerator by accelerating a small charged nuclei (such as Helium, Boron or Carbon) in a particle accelerator to combine with a heavy nucleus (often of a previously made transuranic element) target. The transuranic elements have short half-lives as the atomic number increases. The smaller nuclei combines within the target nucleus, creating a new unstable nuclide or radioactive isotope. The high speeds are required to overcome the…

Sam Kean, a Washington D.C. writer with works in The New York Times Magazine, Mental Floss, Slate, The Believer, Air & Space, Science, and The New Scientist, has created a user-friendly book about how to explain the periodic table and the elements that occupy it by writing the book The Disappearing Spoon: And Other True Tales of Madness, Love and the History of the World From the Periodic Table of Elements. He provides an insight into the world of chemistry that relates to his audience, even…

Dmitri Ivanovich Mendeleyev, born on February 8, 1834, was believed to be the youngest of 14 children. His father, Ivan Pavlovich Mendeleyev was a teacher at a local gymnasium. Around the time Dmitri was born, his father went blind and later died in 1847. Consequently to support the family, his mother Mariya Dmitriyevna Kornileva began working at a small glass factory in a nearby town, and eventually started managing it. On December of 1848, the factory burned down, and the family moved to St.…

Group 1 Elements Referring to the table created from observing the characteristics of the three elements from group 1, Lithium, Sodium, and Potassium, we can see that they all share the appearance of being lustrous and metallic, with a silvery-white presentation, and it is also known that they are all alkali metals. It is also noticed that they are all soft metals easily cut with a knife rather than most metals such as calcium or iron. All three elements are stored within oil, with Sodium as an…

Salbutamol Discovery Chiral chemistry was introduced in 1848 by French chemist and biologist, Louis Pasteur. He discovered this new branch of chemistry after he separated two isomers of ammonium tartate (1). This paved the way for several progressions in the pharmaceutical industry. Although it took approximately a century for scientists to use chiral compounds as effective drugs, they have played a remarkable role in the life of plants and animals (1). The credit for discovering the chiral…

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 1735 by a Swedish chemist, Georg Brandt. Brandt was the first person to discover a metal…
