Chemistry - Essay Example Aluminium is metal with atomic number 13 and it will combine by loosing two electrons. Beryllium and aluminium are metals and will combine with other elements by loosing electrons while oxygen will combine by gaining electrons, therefore our empirical formula will have the following formula: Isotopes of an element have the same number of protons but differ in the number of neutrons; the atomic number is equal to the number of protons therefore Pn has the atomic number 117. Because atoms are neutral then the number of electrons is equal to the number of neutrons. The atomic number is 117; this means that the electronic arrangement is 2: 8:18:32:50:7 this is given by the formula 2N2 which give us the maximum number of electrons in each cell where N is the shell number. We have 6 shells and 7 electrons in the last shell, this means that the element belongs to the 7th period and the 17th group. The empirical formula will be Pn2O7 because oxygen will tend to gain two electrons or loose 6 electrons and Pn will also tend to gain one electron or loose 7 electrons, therefore the highest normal oxide will be loosing Pn loosing seven electrons and Oxygen gaining two electrons. Six decays means loosing six neutrons, and bearing in mind that the number of neutrons is equal to the number of electrons and that the number of electrons is equal to the number of protons then our resulting element will have an atomic number 67-6 = 61.

Product-Harm Crisis - Research Paper Example Product-harm crisis emerges when consumers and the general population publicize the negative effects of a given product in the market (Zhao, Zhao, & Helsen, 2011). Placing a product at the center of product-harm crisis follows the observation that it is either harmful to the consumer, or it fails to meet the required quality and standards of production. In other words, a defective product could spur a highly publicized debate over the underlying negative effects of using the product in question. Once the public becomes engaged in the issue, the affected business enterprise must work towards addressing the problem as well as restoring customer trust. In other instances, a product may not necessarily be defective but a crisis could still occur. Yannopoulu, Koronis, and Elliot (2011) note that product-harm crisis will emerge if the public debates potential product contamination or even reports harm emerging from the consumption or use of a questionable product. In other words, negative publicity is a recipe for product-harm crisis when a given product becomes questionable in terms of quality, standards of production, and the credibility of its benefits to consumers. Following product-harm crisis, voluntary of forced product recalls are highly likely to occur (Vassilikopoulou, Lepetsos, Siomkos, & Chatzipanagiotou, 2009). The affected company could make a proactive move and recall products in question, or the government could force the recall through relevant agencies. Factors and events leading to product-harm crisis are many and different. Both natural and human-driven factors could contribute to product-harm crisis. From a natural point of view, factors beyond the control of the company lead to the occurrence of product-harm crisis. Factors such as floods, earthquakes, mudslides, or volcanic activities are natural events that contribute to product-harm crisis. In essence, the crisis results from the view that the product or products in question fail to
