Symbolic elements

The element Niobium has had an intriguing story, one that continues to this day. In 1734, the first governor of Connecticut, John Winthrop, found a new mineral and named in columbite. He then sent it to a museum in Britain. This new mineral rested in the British museum until 1801 when English Chemist Charles Hatchett decided to analyze columbite. Hatchett determined there was an element in columbite, yet he was unable to isolate it. However, he soon found the element Columbium, after the mineral

very interesting element. It was discovered May 30, 1898 by Sir William Ramsay and Morris M. Travers, who were Scottish and English chemists. Krypton was named from the Greek word ‘kryptos’, which means hidden. It was found when the chemists were studying liquefied air. It is about 0.0001% of the earth atmosphere. It can also be found in some photographic flashes, some fluorescent light bulbs, and can be combined with other gases to make signs with a greenish-yellow glow. Every element is special because

the lab was to mimic the way Mendeleev placed the elements on the periodic table. Mendeleev was a Russian chemist who produced the first orderly periodic table. Frist, the way the periodic table has been classed alongside the atomic sum and the elements with related properties. Second, the objectives are observeing the physical states of common elements, and the progression of the periodic table, lastly speculate by determining the unknown elements established on the observed progression. As a group

“Boron” Boron is one of 118 elements on the Periodic Table and is in everyday life. Boron has a lot of facts to learn about such as, “Who found or created this element?” or, “What uses do this element have?”. Out of all the elements, Boron is an interesting element that stands out from others because it is a powder. This element is also a necessary ingredient that is used in soap. From all the elements on the periodic table, Boron is a unique element in a lot of ways such as the fact that Boron

Carbon, this element has a lot of information to offer. By the end of this essay you will only know a handful of information on carbon. This essay will be talking about where carbon is located on the table, when and who discovered carbon, and how carbon can be used. Carbon is located in group 14 of the Periodic Table of Elements. The classification of Carbon is a non-metal. The name carbon comes from the Latin name carbo for coal and charcoal. The heaviest carbon isotope os C-13, this has seven

is from Latin ‘fluee’ meaning flow. It was discovered in 1886 by Henri Moissan. The melting point of fluorine is -219.6 ℃ and the boiling point of fluorine is -188 ℃, fluorine is in group 7, and is also known as a halogen. It is reactive with most elements. The uses of fluorine include, Rocket fuel, Frosted glass, uranium hexafluoride for nuclear power, Cable insulation, Rain boots, clothes, and refrigerator. The effect of fluorine on the human body include, Enhanced teeth and bones, Prevent tartar

Purpose: The purpose of this lab is to be able to perform four different types of chemical reactions. With the information gained from these reactions, identify the products of the reactants with be identified and balanced equations for the reactions observed will be written. Procedure: Provided by Teacher. Data and Observations: Reactants: Observations: Products: Mg + O₂ Part A) The sample began to glow orange. As it increased in heat, it began glowing white. It gave off a smoke. After the heat

an original, animated series that premiered on the Nickelodeon Network in 2005. The Last Airbender is a classic coming-of-age tale that beautifully portrays the dynamics of family, friendship, duty and love, while simultaneously capturing mature elements of race and gender. All in all, the story is mostly built upon Eastern influence with aesthetic inspiration drawn from China, Japan, India, the Inuit, and many other cultures. Religious influences also stem from Hindu and Buddhist beliefs which teach

The three elements that I will be looking at are Krypton, Arsenic, and Potassium. These elements are all very different but share some similarities even with their separate placement on the periodic table. I chose these elements because they are the most different of the six elements that I chose to do this project on. Arsenic is the first element we will be looking at. Arsenic is a metalloid because it shares some characteristics with metals and some with nonmetals. Arsenic, like Calcium, is a

discover that patterns would become apparent when elements were classified to their properties. Mendeleev’s adjustment of elements was the one and only due to his idea of leaving blank spaces for elements he believed were undiscovered in 1869. The purpose of the Mendeleev Lab of 1869 is to use knowledge of the periodic table in order to identify the undiscovered elements. Ultimately the whole idea is to observe, and draw conclusions to identify the elements. For instance, observing properties, samples
