to drink because of the water’s bitter taste. However, the farmer noticed the water seemed to heal scratches and rashes. The words spread out. Eventually it was recognised to be magnesium sulphate, MgSO4. Until 1755, it recognized magnesium as an element by Davy” ( Marker Winter) You can find magnesium around you such as in ladders, laptops, televisions, cell phones, luggage, aircraft and missile components. Human cannot live without magnesium. “Magnesium is a material for people looking for…

5-CinthiaV-Selenium The name of my element is Selenium. The element symbol is “Se”. Selenium was discovered in Sweden by Jons Jacob Berzelius in 1817. Selenium is an origin for a greek word meaning moon. Selenium has four energy levels. In the first energy level, it has two electrons. The second energy level has eight electrons. The third energy level has 18 electrons. The fourth energy level has six valence electrons. Selenium has forty-five neutrons. Selenium has the…

Introduction: The periodic table is a table of the chemical elements in which the elements are arranged by order of a atomic number. The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in…

I read the book A Tale of Seven Elements by Eric R. Scerri. This book was published on June 20 of 2013 by Oxford University Press, USA and it contains 270 pages. A Tale of Seven Elements is a non fiction chemistry book. Overall this book talks about how seven elements - protactinium, hafnium, rhenium, technetium, francium, astatine and promethium - were discovered. These elements are referred to him as infra-uranium elements. Each element has its own chapter with a description to how it was…

One of the earliest metals to be discovered, lead has a long history with mankind. It was first discovered around 7000 BC as a byproduct of silver smelting. Lead is metal known for its resistance against corrosion, malleability, and low melting point. Mined all across the world, lead was one of the most important metals in ancient times. Although lead was toxic, it was used widely, particularly in the Roman Empire. Through its uses and toxicity, lead affected the classical era in a drastic way.…

SaskWater has received a Request for Service from the Town of Birch Hills requesting a peak flow of 130 igpm. An assessment was performed includes two of SaskWater existing systems. Option #1 the Melfort Regional Treated System (CLPOWSS); three scenarios were considered while investigating the CLPOWSS. Scenario #1 connects the Birch Hills community with the CLPOWSS, plus twining 5.5 km of the existing pipeline between Melfort and Kinistino, which would allow for 100% of average daily…

Many chemicals are safe to handle but negatively impact the environment in the long run. Other chemicals such as arsenic are toxic even in the smallest amounts. Mercury is a natural element that occurs throughout our environment and solar system. It has unique properties (i.e liquid metal at room temperature) and can be found in very small concentrations in many rocks and is the main component of the mineral cinnabar. Natural background levels can be detected in soils, living organisms, air, and…

Introduction: When somebody was eating at a popular restaurant they suddenly felt ill. Fortunately a white powder was discovered on the victim leading them to believe that the powder was the cause of the victim feeling ill. The restaurant narrowed the substance to be one of the white powders they use in the restaurant and compare it to the mystery powder. The five white powders were; icing sugar, cornstarch, aspirin powder, baking soda, baking powder. To test it out they mixed each white powder…
