Lithium Though the drug lithium is used for a number of disorders ranging from acute depression to eating and personality disorders (Paykel, 1992), it's primary use is for bipolar disorder, also known as manic depression. Patients with bipolar disorder "between two poles: depression and its opposite, mania" (Kalat,2004), often with periods of normal behavior in between (Jamison,1993). In addition, the patient is also prone to "mixed episodes" in which symptoms of both mania and depression
ike the other alkali metals, lithium has a single valence electron that is easily given up to form a cation. Because of this, it is a good conductor of heat and electricity as well as a highly reactive element, though the least reactive of the alkali metals. Lithium's low reactivity compared to other alkali metals is due to the proximity of its valence electron to its nucleus (the remaining two electrons are in lithium's 1s orbital and are much lower in energy, and therefore they do not participate
This was the first discovery of Lithium. From the Greek word "lithos" meaning "stone", it was so named due to the fact that it was discovered from a mineral source; whereas the other two common Group 1 elements, Sodium and Potassium, were found in plant sources. Its symbol, Li, was taken directly from its name. Soon after stumbling upon Lithium, Arfvedson also found traces of the metal in the minerals Spodumene and Lepidolite. In 1818, C.G. Gmelin discovered that Lithium salts color flames a bright red
Relative Atomic Mass of Lithium Background information I’m going to produce a piece of coursework, which determine the relative atomic mass of lithium. Two methods are going to be used to approximate the relative atomic mass of lithium. 1) In the first method the RAM (Relative atomic mass) of lithium is determined by the Volume of hydrogen gas produced. 2) In the second method the RAM of lithium is determined by titrating the lithium hydroxide produced.
Determining the Relative Atomic Mass of Lithium An experiment has been carried out to determine the relative atomic mass of Lithium by using two different types of methods The first method that was carried out was to determine the volume of Hydrogen produced. In this experiment a fixed amount of Lithium was used, in my case it was 0.11g. At the end of this experiment, the volume of Hydrogen gas I collected was 185cm³. Then using the solution of lithium hydroxide made from experiment one,
Determination of Relative Atomic Mass of Lithium Evaluation: In general the accuracy of the experiments was good. However with practice, the accuracy could be improved; accuracy being how close the results are to the real answer. I think I have carried pit the experiment as well as I possibly could at the time with the given conditions and time period allowed. I have gained precise results from the practical. However, looking back at the analysis section, the relative atomic mass values
Lithium and Bipolar Disorder INTRODUCTION The drug lithium has been used for a variety of disorders such as gout, diabetes, and epilepsy for over 100 years. It was not until 1949 when John Cade discovered that lithium had a calming effect on guinea pigs that the possibilities of it being used for mania were explored (Paykel, 1992). Since then, lithium has been established as one of the primary treatments for manic depression disorder. In the body of this paper we will explore the
Atomic Mass of Lithium Introduction My aim of this experiment will be to determine the R.A.M using two separate methods In the first method I will dissolve a piece of lithium of a known mass in water, I will then collect the hydrogen gas produced, which can be used to calculate the relative atomic mass of Lithium. The balanced equation of our reaction is shown below; [IMAGE]2Li + 2H2O 2LiOH + H2 In the second method I will do a titration experiment of lithium hydroxide(produced
Lithium is used in many items we use daily, but it may not be the best for us to use (Wanger 202-206). Lithium’s effects can be sorted into the categories; political, economic, environmental, social, and technological. Of these the economic and environmental are the most important to understand. The environmental and economic effects can connect to social, political, and technological effects. We should stop using lithium batteries because the effects will add up and create problems for our society
Lithium batteries are the batteries that have lithium as an anode. These sorts of batteries are additionally alluded to as lithium-metal batteries. They stand separated from different batteries in their high charge density and high cost per unit. Depending upon the outline and synthetic mixes utilized, lithium cells can create voltages from 1.5 V to around 3.7 V. A lithium-ion battery is a kind of rechargeable battery in which lithium ion move from the negative terminal to the positive anode while
Lithium-ion batteries were commercially introduced for the first time in 1991[1]. Since their introduction, they have revolutionized consumer electronics by becoming the dominant power-source for devices such as laptops and cell phones. This is mainly due to their superior energy-density compared to other energy sources. Lithium-ion batteries are becoming the subject of even greater interest these days, since they are the power-source of choice for electric vehicles (hybrid and otherwise). This is
will discuss the primary limiting factors of lithium-oxygen battery. Overpotentials Overpotential problem occur on lithium-oxygen batteries because the charging and discharging potentials deviate from standard potential. The overpotentials are the extra energy required to drive the reactions at a specific current density. Then, capacity of the battery is dependent on the clogging of reduction products in the porous cathode. In order to dissociate the lithium peroxide on charging, large potential difference
another, all of those three devices share one item in common at the very least and that is a Lithium-Ion Battery. Lithium-Ion Batteries are extremely popular in the technology industry for several reasons. First off, they are much lighter then other batteries because they are made with lightweight lithium (a light and reactive metal) and carbon. Second of all, they give the most power per pound. A Lithium-Ion Battery stores 150 watt-hours per kilogram. Compare that with a Nickel-Metal Hydride Battery
Galvanic Cell. In this article, the chemistry, cost and practicality, impact on society and environmental impact of a dry cell and lithium-ion cell will be discussed. Chemistry and structure Definition of a Galvanic cells A galvanic cell is an electrochemical cell where reduction-oxidation reaction spontaneous to originates electrical energy. Both the dry cell and lithium cell generates current so they can be defined as galvanic cell. Chemistry of the dry cell The dry cell battery is one of the
History of Lithium-Ion Batteries Rechargeable battery evolution accelerated as the world transitioned to instruments enabled by silicon microchip technology from those of bulky electrical components. Mobile devices were designed to be powered by lightweight energy storage systems. The development of batteries for this rapidly evolving market was challenging: • The nickel cadmium battery had been the only option for modern electronics for many years. It was a great improvement over carbon batteries
Presumably all of them loved to eat lamb meat. They fed them tainted lamb, wrapped in fresh lamb hide. The meat itself was not toxic to the long-term health of the coyotes that devoured it. Instead, it was laced with lithium chloride, which causes vomiting. One assumption made was that the lithium did not actually affect the taste of the meat. Therefore, the coyotes actually did consume the meat, and uniformly became sick after eating the lamb. As a result of associating the meat with vomiting the coyotes
Fireworks When thinking of fireworks, many peoples first instinct is to picture bursts of color accompanied by the loud noises of the explosions. Not many people think of what all goes into the production of a firework and how it works. But then again, why would you when you could be enjoying a beautiful firework display? Exactly, you wouldn’t. Let me tell you a little bit about what goes into fireworks and why you see what you see. It will make you appreciate the fireworks even more than you already
As very clear was shown in the recent years - the battery soft shorting and overheating problem cannot be identified at a time when battery was manufacturing. Only after prolonged cycling (usage) this phenomena may occur. Market forces battery manufacturers to extend battery life, achieve higher energy densities and faster charging times. This will force engineers to design higher density electrode and use thinner and higher porosity separators. The fact is the energy densities are double what they
metals with lithium, the first in the group. Lithium caused a strong reaction when added to the water. The water bubbled and the reaction made a sizzling noise. The lithium piece at the bottom of the tube spun around until it dissolved. When we added the burning splint, it made a popping noise, but rather than immediately extinguishing, a red flame was briefly lit on the mouth of the test tube. After we added the phenolphthalein, the solution became a light pink color. After testing lithium, we tested
day in a metal shop in Utah. The metal shop holds lots of metals such as Titanium, Steel, Aluminum, Copper, Iron, And Lithium. Lithium is a shiny, silver colored, soft metal. All of the other metals make fun of the little chunk of Lithium because they think that he is to soft to be a metal and that he can’t be used for anything. They don’t even think he qualifies to be a metal. Lithium has been taking this baloney for about a year now and he cries tears about it every night. He doesn’t even know what
