Essay on Analysis of the Oxygen Group on the Periodic Table

Chapter one of The Disappearing Spoon informs us of the information hidden in the periodic table, and why the periodic table is arranged the way it is. Through its pages it explained the formation of the periodic table such as its shape, trends, and etc. The pages also tie into one or more learning goals in this unit. A periodic table is not just a chart with things splashed onto it, it is a chart that was thoroughly arranged based on the trends, the characteristics, the description, and formation of an element.

The elements were organized by Dimitri Mendeleév. He organized them by properties (columns), groups (horizontal), and atomic number (the number of protons and electrons). This became known as the Periodic Table. And currently there are 118 elements. He also found gaps in which elements that were yet to be discovered were to go, three of these unknown elements were found and identified in Mendeleév's lifetime. The elements today are used in everything and 75% of the 118 elements are metal.

How can one human mind organize and memorize over 100 elements? In 1869, Dmitri Mendeleev, a Russian chemist and inventor, was credited with creating and publishing the Periodic table. The Periodic table is an arrangement of the chemical elements discovered on earth. These elements are organized by their atomic number and similarities between chemical properties. The Periodic table holds 118 elements which can be broken down into smaller classifications, groups (vertical), periods (horizontal) and blocks (adjacent). In this paper, we will zoom in one unbelievable element Osmium, which is usually lost in the mix.

Noble gases are the most stable elements of the periodic table. They have many qualities that make them unique to other elemental groups. Noble Gases have many important differences that should be noted when studying the periodic table; such as the number of valence electrons and location, their state of matter, and their reactivity.

In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

O and S belong to the same group. How many valence electrons does each have?

Oxygen is one of the reactants necessary for respiration therefore it is essential for all living organisms. Oxygen is produced through the process of photosynthesis where energy from the sun is converted into chemical energy in the form of glucose.

I choose Sulfur because of it’s bright yellow color which really catches your attention. I also found it very interesting how much damage sulfur really is to the human. Plus is a very hard element to locate due to the fact that it can mainly be found by hot springs or volcanoes. Sulfur, also spelled sulphur, is a chemical element with the symbol S and atomic number of 16. It is an abundant non-metal and at room temperature is a bright yellow crystalline solid. Chemically, sulfur combines with all elements except for gold, platinum, iridium, nitrogen, tellurium, iodine, and the noble gases. Sulfur forms over 30 solid allotropes, more than any other element. Allotropes are different forms in which an element can exist. I picked this element because

chemical element here on our own planet Earth. Though it is a rare, unreactive noble gas,

The five elements will be explained in the following

Helium is a lighter than air gas. It has a 4.00260 atomic mass while air or oxygen has a 15.9994 atomic mass . According to Jefferson Lab editor Thomas Jefferson National Accelerator Facility “Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth.” (2017,[online]). Oxygen is one of the most common gas and every living thing needs it to live. “Oxygen is written as

The book “The Periodic Table” by Primo Levi is undoubtedly a masterpiece. It showcases the enthusiasm, the level of dedication, and passion successful chemists such as Primo Levi himself had for the field of their expertise. The way Primo Levi has related the troublesome times and events he had to face in prospect with the elements of the periodic table is laudable. Primo Levi is surely an inspiration and a perfect example of prodigy and passion. Despite the challenges and the hardships inflicted on him by the bigoted group of Germens, he still managed to emerge as an exceptional chemist and an author who made great contributions to the modern chemistry as we now know it.

The construction of the Periodic Table of Elements was prior to the discovery of the individual elements. Elements such as silver, gold, tin, copper, lead and mercury have been known for centuries. In 1649, the first scientific discovery of an element was made by Hennig Brand when he discovered phosphorous. Prior to Brand’s discovery, chemists had acquired an immense body of understanding concerning the properties of elements and their compounds for the next 200 years.

Fire is explained in a tetrahedron of necessary requirements a fire needs before it is able to spring to life. First, is sufficient fuel. Different types of fuel coincide with different types of terrain. In dry, sparse areas, dead grass and shrubs provide the best fuel. In lush, green forests, pine needles, leaves, twigs, and other such things typically underfoot makes for the best fuel . Second, is an oxidizing agent. This could be the oxygen

Iron is an important element to the scientific community, especially those involved in the branch of chemistry. Consequently, humans rely on iron for many different things. Iron is diverse from all other elements with regards to its natural occurrence, historic and contemporary uses, the origin of its name, and when, how, where, and by whom it was discovered. It also has unique characteristic physical and chemical properties. Without the discovery, and distinctive properties of iron, life on Earth would never be the same as it is now.
