INTERPRETING THE PERIODIC TABLE Partner’s name: Faranak Hajikhan, Pablo Moncada, Albina Contreras and Karla Santos Title: Interpreting the Periodic Table Date: 12-18-14 Subject: Honors Chemistry / Period 5 Introduction: The periodic table is a table of the chemical elements in which the elements are arranged by order of a atomic number. The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number…

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 interested to learn more. The bromine name was derived from the word bromos, meaning “bad smell” or “stench”. Whilst being in group 7, Bromine contains the…

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…

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.…

In this class, the diverse learner pairs with peers within the group who help if the diverse student has a problem understanding. Scientific discourse is written in the carbon atom group worksheet. This is one of Hanauer 's components. If the diverse student cannot understand the worksheet, the peer pairing helps the diverse student with language or reading. The teacher monitors visiting each group asking questions. Teacher looks for understanding in the diverse learners. If the diverse…

Not only he concluded that elements should be classified by its atomic number. He stated that the atomic number must be the number of positive charges on the nucleus, Mosely helped to refine the order of elements in the periodic table and this revealed the flaws in the periodic table. It also helped scientist to utilize the technique of X-ray spectroscopy to analysis and identify new elements. Glenn Theodore Seaborg (1912-1999) In 1941, Seaborg had discovered the first transuranium element…

electrons in the valence shell for an element is clearly seen in this graph. The lowest point of each peak coincides with the Group I alkali metals. From there on, the electron count climbs until a full shell is reached at eight electrons, i.e. the noble gases who have full outer shells. The full shell signals the end of a Period at Group VIII, and then it begins again in Group I in a new Period. There is an anomaly from Scandium (Sc) to Zinc (Zn) where the electron count doesn’t rise, it hovers…

the elements on the periodic table. The Disappearing Spoon focusses on the history of the Periodic Table by telling stories that show how each element affected the scientists that discovered it. For each element, Kean supplies an extensive backstory for its foundation, the common (or uncommon) uses of the element and other useful factoids about the matter. The author begins the novel with a physical description of the Periodic Table as a whole; he discusses the names of the groups of elements…

Introduction Fluorine is the 9th element on the periodic table. It is a light yellow gas and is most commonly known for helping your teeth. I choiced this element because it has the highest electronegativity. But what other traits does fluorine have? Read my ABC book and find out. A is for… Atomic number The atomic number of fluorine is 9. The most common isotope of fluorine is 19F and 18F. Fluorine is more stable in when it has 10 neutrons. Fluorine is a halogen and is placed on…

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…
