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

Since the electrons in the electron sea can move freely, metals conduct electricity very easily, unlike molecules, where the electrons are more localized. Metal atoms can move past each other more easily than those in ionic compounds allowing the metal to be hammered into sheets or drawn into wire. Different metals can be combined very easily to make alloys, which can have much different physical properties from their constituent metals. nickel, and other metals are also often added to iron to make steels of various types. Brass is an alloy of copper and zinc which is used in plumbing fixtures, electrical parts, and musical instruments. Bronze is an alloy of copper and tin, which is much harder than copper; when bronze was discovered by ancient civilizations, it marked a significant step forward from the use of less durable stone tools. The metalloids are intermediate in their properties. In their physical properties, they are more like the nonmetals, but under certain circumstances, several of them can be made to conduct electricity. Ionic bonds form when there is a transfer of electrons from one species to another, producing charged ions which attract each other very strongly by electrostatic interactions, and covalent bonds, which result when atoms share electrons to produce neutral

    The purpose of this lab was to analyze and examine periodic trends of the first 36 elements that are on the periodic table. Trends that were analyzed and examined are the atomic radius (AR) and the first ionization energy (IE) of the 36 elements. The hypothesis for this lab was that the elements that are in the groups that had the highest atomic radius would be in the same groups as those who have the the highest first ionization energy and the groups who have the lowest atomic radius would be in the same groups as those elements who have the lowest first ionization energy. In order for the lab to be completed, a chart that was split into four sections was made to collect all the necessary data that is needed to make the graphs. After the data has been collected, a graph that contains both trends was made on a piece of graph paper.…

    The attraction that holds the oppositely charged ions together in the ionic compound is called an ionic bond. Ionic compounds are hard, brittle solids with high melting points. Most ionic compounds are also electrolytes, which are compounds that separate into ions when they dissolve in water, producing solutions that conduct electricity. In addition, most ionic compounds form three-dimensional crystals, in which many of each kind of ion in a fixed ration are held together by their ionic bonds. Sodium hydroxide is an ionic compound, which sodium is the metal cation (Na+), and hydroxide is the non-metal anion (OH-), more specifically, sodium Hydroxide’s hydroxide is a polyatomic ion, an ion made up of more than one atom that acts as a single particle.…

    Disappearing Spoon Essay Tanner Rapp In this book about the periodic table and how each element was discovered and how it affected each scientist when they discovered it. The story shows scientist such as Maria Goeppert, Dimitri Mendeleev, Robert Bunsen, Fritz Harbor, William Crookes, and many more. However, in this essay I am going to write about Dimitri Mendeleev, Robert Bunsen, and Fritz Haber. Dimitri Mendeleev is a very important scientist when it come to the periodic table, he is known as the, “creator” of the table.…

    The book, The Disappearing Spoon by Sam Kean explores each of the elements on the periodic table. The Disappearing Spoon focusses on the history of the Periodic Table by telling stories that show how each element affected the scientists that discovered it. For each element, Kean supplies an extensive backstory for its foundation, the common (or uncommon) uses of the element and other useful factoids about the matter. The author begins the novel with a physical description of the Periodic Table as a whole; he discusses the names of the groups of elements and their corresponding properties, atoms and their three major sub-particles, the activity of electrons, and the organization of the Table. Sam Keane then goes on to talk about each element of the Periodic Table, and how that…

    People find out new things about the world every day. Scientific findings are almost never final. Experiments can verify or shatter what we perceive as facts of life. Atoms are an example of this. Thinkers and scientists from throughout time have been theorizing and experimenting to find out what an atom is made of.…

    The 3 elements that were picked for the experiment share similar group and periods. The elements Magnesium (Mg) and Calcium (Ca) have similar group, but their reactivity are different. The reason for this is that the atomic radius trend decreases as you go across the group but increases as you go down the group. Calcium is further down than magnesium, which mean it will have a bigger atomic radius. The definition of the atomic radius is the distance from the nucleus to the outside edge of the electron cloud, this means that the bigger the atomic radius is, the harder for the positive nucleus to pull the negative electrons in because of electron shielding, meaning that the electron in the lower energy level is in the way of the radius and the electrons in the higher energy level.…

    Moreover, metallic bonds have a simple crystal lattice in solid state and are the weakest primary chemical bonds. Hence the reason to why pure metals are dissolved with other elements such as: carbon for mild steels. Metal alloys have increased strength and hardness. The structure of alloys reduces the space between each ion, so there is less space for delocalized electrons and it improves the chemical bond with each element within the…

    Copper has antimicrobial properties and kills bacteria, viruses and yeasts on contact. As a result, copper can even be woven into fabrics to make antimicrobial garments, like socks that fight foot fungus. About two-thirds of the copper on Earth is found in igneous (volcanic) rocks. About a quarter occurs in sedimentary rocks, according to the USGS. The metal is ductile and malleable and conducts heat and electricity well, explaining its use in electronics and wiring.…

    The elements sodium and chlorine show emergent properties, because when sodium is alone it's just a metal and chlorine is a poisonous gas. When you combine the two with an ionic bond the emergent properties are shown, because they come together to form table salt, but on their own this wouldn't be possible. 2.1.2) Yes, even though organisms only require it in small amounts it is still essential because it contributes to the organism's development. 2.1.3)…
