2. The reactivity of the metal increases with each period it goes down. Magnesium is the least reactive and is in the third period with an atomic number of 12. Calcium is slightly more reactive being in the fourth period and having an atomic number of 20. Barium is the most reactive because it is in the sixth period and it has an atomic number of 56. So the farther down in the group they go the more reactive they are.…

Introduction: The purpose of this lab was to find the relative solubilities of some salts of the Alkaline Earths and use that information to find the order which they appear in the periodic table; also use that information to efficiently find an unknown alkaline earth halide. Also to find the relative oxidizing powers of the Halogens given and using that information finding the order of the Halogens in the periodic table; also use that information to efficiently find an unknown Halogen.…

One of the many elements on the periodic table is Aluminum. Aluminum is the 13th element, and it is located in period two and group thirteen. Aluminums symbol is Al and it has an electron configuration of [Ne] 3s2 3p1. Aluminum also has an atomic mass of 26.982 and its atomic number is 13. This element was discovered by Hans Christian Oersted in the year of 1825, and was named by the English chemist Sir Humphry Davy (Helmenstine, 2012). Its name ‘Aluminum’ came from the Latin words ‘alumen’ or ‘alum’, which is an astringent and dyeing mordant. Originally, Davy called it “Alumium’ but the publishers later changed it to Aluminum, and that’s how it remains in the United States (N/A, n.d.).…
Firstly, they do have some uses. For example, americium is used in smoke detectors and plutonium is used as a fuel in nuclear power plants and nuclear weapons. Over one-third of the energy produced in most nuclear power plants comes from plutonium. [12] Secondly, the superheavy elements discovered are getting closer and closer to the fabled ‘island of stability’.…
What are the differences between technical writing and other forms of writing with which you are familiar? Which is more persuasive: technical writing or expository writing? Explain your answer. Which type of writing have you seen used more often in the corporate environment?…
Atoms are the smallest entities which resemble the properties of an element and cannot be broken down into smaller parts. Molecules are formed when two or more atoms are combined. This formation can happen in a variety of ways. When two oxygen atoms join O2 is formed, and when three oxygen atoms join O3 or ozone is formed. Both of these have different properties. Different atoms can also combine to form molecules. Hydrogen combines with sulfur to form H2S and hydrogen and oxygen also combine to form H2O.…
Despite the strong dominance of science in The Periodic Table, Primo Levi manages to write a compelling and moving novel about love and friendship, while simultaneously exploring the intricate world of chemistry. Friendship and chemistry? One might ask themselves what correlation these two contrasting, yet essential aspects of life might have between one another. Through complex chapters such as “Hydrogen”, “Iron”, and “Cerium”, it is revealed that the profound friendships one contructs, regardless of how momentary they might be, have the power to move hearts and touch lives. The elements of the Periodic Table are constantly forming bonds with one another, whether they are covalent,…
The atom is used for many things in today's world. For example nuclear power plants are a much cheaper way of creating electricity. However, not only are they cheaper but they also help conserve the earth's resources. Instead of burning millions of metric tons of coal in a year and polluting the air with harmful carbons, nuclear plants use fuel rods as their energy. These rods heat water, create steam, and generate electricity, while not giving off any harmful gases.…
Chemistry is very important in our lifes. If you really begin to think about how things work, everything is made up from a formula and works together through chemical reactions. Our foods, our bodies, health care and beauty products, medicines, some factories that use fuel for power, and even cleaning supplies. All of these things have chemical reactions that relate our everyday use of household products or even our jobs to chemistry.…
Sodium, one of many elements in the periodic table is being used in everyday life, it is also an essential element within your body. It is just another element, but one of the differences is that this element is something that most people consume every day. Sodium has played an important role in everyday life because of its uses in medicine, industry, and agriculture(Shriver).…
Copper is one of the most important transition metals for human life. Copper is used in our everyday life from house items, conducting electricity, and money. Copper is taken for granted even if it is used every single…
What is Krypton? Some might say it is the planet Superman is from, but it is actually a chemical element. Krypton is one of the rarest gases on Earth which makes it very expensive. It can also be found in Mars’s atmosphere, but only makes up 0.3 parts of a million. Krypton was discovered in 1898 by Morris Travers and Sir William Ramsey. It was named after the Greek word, kryptos, which means “hidden”.…
