The purpose of this lab was to analyze and examine periodic trends of the first 36 elements that are on the periodic table. Trends that were analyzed and examined are the atomic radius (AR) and the first ionization energy (IE) of the 36 elements. The hypothesis for this lab was that the elements that are in the groups that had the highest atomic radius would be in the same groups as those who have the the highest first ionization energy and the groups who have the lowest atomic radius would be in the same groups as those elements who have the lowest first ionization energy. In order for the lab to be completed, a chart that was split into four sections was made to collect all the necessary data that is needed to make the graphs. After the data has been collected, a graph that contains both trends was made on a piece of graph paper.…
In this Beanium lab, the objective was to make sense of the numbers used to calculate average atomic mass. By separating, counting, and weighing beans we were able to create the numbers used to calculate the weight of one bean. From there, we could use the total number of beans to produce the percent abundance for each type of bean. These were the numbers that we had to produce in order to understand how and why there are many types of isotopes for each element. In doing this lab, we can think through the importance of finding the average atomic mass and not just using a single isotope for an element.…
ISOTOPE EXPERIMENT- BEANIUM Introduction This beanium experiment was performed to display a greater understanding of isotopes of an element. Atoms that belong to the same element with the same number of protons but differ in numbers of neutrons are called isotopes.…
Fluorine isn't simply an “F” on the periodic table. It is much more. In fact, fluorine is the most important element of any element on the periodic table. It indeed does not belong to the great collection of Noble Gases in Group 8A of the periodic table, but its position in Group 7A alongside the elegant Noble Gases solidifies it as one of the leading significant elements at our disposal. For that reason, in the the showmanship of element practicality, fluorine is an outstanding competitor!…
Gallium is one of those elements that is used in industry every day. Gallium was discovered in Paris at the private laboratory of Paul-Emile Lecoq de Boisbaudran (1831-1912) at 3 a.m. on August, 1875. He observed a new violet line in the atomic spectrum of some zinc he had extracted from a sample of zinc blende ore (ZnS) from the Pyrenees. He knew it meant that an unknown element was present. Gallium comes from Gallia, the Latin name for France.…
Otto Hahn was a German chemist who discovered fission, fission is the action of dividing or splitting something into two or more parts. When Hahn discovered nuclear fission he unintentionally discovered how to create an atomic bomb. Hahn discovered nuclear fission by having a speed neutron hit a uranium atom, the uranium atom spit. When the speeding neutron hit the nucleus of the uranium atom the atom stretched until it split.…

Fluoride is one of the most toxic substances known to humans. The substance is made up of a salt of hydrofluoric acid consisting of two elements, one of which is fluorine. You may have heard of this toxic acid, that is because it is commonly used at dentist offices. Fluoride is used by dentists to clean bacteria off your teeth and reduce tooth decay. Studies have shown that for years, the government has been poisoning the public water supply without citizens explicit consent.…
Nuclear Fission was discovered using uranium in 1938 by Otto Hahn and Fritz Strassmann, Scientists from Germany. Fission is the process of splitting an atom,…
Outside of basic scientific research, francium is essentially useless in the infinitesimal amount that exists. Francium can only be found in miniscule amounts in uranium ores. It can also be made artificially by bombarding thorium with protons.…
Fluorite, also called fluorspar, is a mineral that is composed of calcium and fluorine. Pure fluorite is colorless. Fluorite is known as the most colorful mineral in the world. Each colored fluorite has its own name. The most common colors for fluorite come in purple, blue, yellow, or green (King, Fluorite.)…
Fluoridation of Drinking Water Jack Barth, AP Chemistry Water fluoridation is a common practice in many communities, both in the United States and worldwide. In 2012, 75% of American communities had access to fluoridated drinking water (Center for Disease Control and Prevention, 2015). The CDC also touts the many advantages of fluoridated drinking water, such as lowered tooth decay among families and fewer dollars spent on dental procedures. However, many individuals and medical institutions have spoken out against water fluoridation. There is much controversy surrounding this issue.…
Thulium is element 69 on the periodic table with 100 neutrons, 69 protons, and 69 electrons. The Swedish chemist Per Teodor Cleve discovered Thulium by extracting it from Erbium in 1879 at the University of Uppsala, Sweden. Since thulium is expensive, it is not practical for any use. On the other hand, if we ignore the price, thulium is good as an energy source, in microwaves, a radiation source in x-rays, and for doping Something interesting about fiber lasers. The only threat of thulium is to humans.…
According to chemistry professor Carolyn Ruth, author of “Where Do Chemical Elements Come From?,” all fundamental elements are fabricated from the explosion of stars, commonly referred to as supernovas. Essentially, Ruth contends that a newborn star is primarily…
Femicide has been used to describe killings of women by intimate partners and family members; it has also been used to describe gender-related killings in the community The term femicide was introduced in the last century to describe killings of women that were gender related in order to recognize the impact of inequality and discrimination, identified internationally as a root cause of violence against women…
