Abundance of the chemical elements

Cast Iron is processed to remove impurities or slag and is turned into a steel alloy. Therefore steel is an alloy and Iron is an element. Steel is also called as an alloy of iron, with the content of carbon controlled. 4% of carbon in Iron makes it Cast Iron and when the carbon content is less than 2%, the product is steel. Cast Iron is made from pig iron, which is the by-product of…

that the 1.1 billion men, women and children who have no access to fresh water according to the U.N will increase in the future. If there isn’t enough water to support the human population then it will have a water scarcity which is “the volumetric abundance of water supply which then leads to water stress. Water stress is the ability or lack thereof, to meet the human and ecological demand of water” (Schulte, 2014). This is because the rivers and lakes are drying up and it would not be able to…

NiCd is the chemical abbreviation for the composition of Nickel-Cadmium batteries, which are a type of secondary (rechargeable) batteries. Nickel-Cadmium batteries contain the chemicals Nickel (Ni) and Cadmium (Cd), in various forms and compositions. The nickel-cadmium battery, invented by Waldmar Jungner in 1899, offered several advantages over the then only rechargeable battery, lead acid, but the materials were expensive and the early use was restricted. Developments lagged until 1932 when…

What is a chemist? A chemist is a scientist that studies, physical and chemical properties of different forms of matter. There are two profound chemist whose findings were crucial to today's understanding of chemistry. There names were Marie Curie and Dimitri Mendeleev, both chemist made significant impacts on modern day science and society. Dmitri Mendeleev is responsible for the creation of the periodic table, while Marie Curie is responsible for discovering radioactivity, which advanced the…

1. Is mercury an appropriate target for AGI? Why or why not? Please clearly cite examples for your reasons. (10 points) There are many reasons that mercury is an appropriate target for AGI. • Both companies are in the same industry of footwear products. • First off the two companies have differentiating strategies and markets that they sell to. AGI will be adding a new market to their company goals and increasing their revenue streams. • AGI strives in the casual footwear segment with a…

Our prior knowledge and mindset can define the way we approach new knowledge and experiences; we see what we believe, each letting our schemas have an affect on the conclusions that we draw from situations. Our perception of what occurs and the way we go about our motives are based off of a previous inclination or concept towards the situation we are preparing to encounter. This schema is useful in helping us organize and interpret information based off of our previous experiences or lessons,…

The only difference is that there has been many more elements added. Mendeleeve also had predicted a lot of the characteristics and properties of elements that would fill up some of the spaces that he left in his periodic table. Many scientists were later able to find out if these predictions were correct or not. As it turned out, most of Mendeleeve’s predictions were correct and that made it easier because they could just leave that element in that space. Mendeleeve was very smart when…

Zinc is the member of the first row transition series of elements, consisting of Sc, Ti, Cr, Mn, Co, Ni, Cu, Zn, Cd and Hg. All these elements belong to group 12 of periodic table. Zinc has an atomic number 30, an atomic mass of 65 and one main oxidation state (+2). Zinc has five nature isotopes . Zinc is the 24th most abundant element in the earth’s crust. Its properties is very similar to Cd.Zinc is very useful in biological systems. Zinc also is involved in many biochemical processes that…

Why didn't scientists at the University of California at Berkley call element 97 and 98, Universitium and Ofium, respectively? (1 mark) Scientists at the University of California at Berkeley did not call elements 97 and 98 as ‘Universitium’ and ‘Ofium’ because they were worried that New Yorkers might name the next two ‘newium’ and ‘yorkium’, making the phrase “University of New York” rather…

also create elements. Currently, there are organized on a chart known as the periodic table, one such element is Germanium. In fact, Germanium has a symbol known as Ge. A symbol is a shorter way to represent the element. All elements have a symbol, atomic mass, atomic number, and a number of protons, neutrons, and electrons. Germanium’s atomic mass is 72.64, this is the amount of mass in each atom that’s in Germanium. The atomic number for Germanium is 32, which represents where the element is…
