Sulfur Natarsha Harris Introduction to Chemistry Professor Michael Jones June 7, 2017 Sulfur goes back to the ancient times but it was called brimstone. In 1979, a French chemist named Antoine Lavoisier recognized sulfur was an element and added it to his list of elements. The element sulfur is considered a nonmetal and is the 10th most abundant element in the universe. On the periodic table sulfur is in group sixteen and it is a representative element. Sulfur has an atomic mass of 32.07 with an atomic number of 16. There are three energy levels for sulfur the first energy level is two, the second energy level is eight, and the third energy level is six. The physical properties of sulfur are a bright yellow powder. When it is burned you will see a clear blue flame and it has a strong odor. Sulfur has a melting point of 239.38 degrees Fahrenheit, a boiling point of 832.28 degrees Fahrenheit, and the density is 2.67 g/cm. Sulfur has sixteen electrons, protons, and neutrons. When sulfur reacts with the air it produces a gaseous dioxide. It does not react with water under normal circumstances. Sulfur reacts with halogens when it is heated. Sulfur makes up almost 3 percent of the Earth’s mass. At The sulfur in volcanoes will turn into a gas. When sulfur comes into contact with the cold air it turns back into a solid. Sulfur has four isotopes which are sulfur-33, sulfur-34, sulfur-35, and sulfur-36. Sulfur-35 is a radioactive isotope, it is used commercially to make rubber and gunpowder. It is an essential and a vital nutrient for crops, animals, and people. It is in breast milk and can also be used as a fertilizer. Sulfur is in our food and we are exposed to it in our diet. Sulfur is also in some proteins and vitamins. Some people have even sprinkled sulfur in their yards to get rid of snakes, but it should not be used if you have pets or
Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted
Sulfur is found in the cells of all living organisms and plays a critical role in the oxygenation and detoxification of all cells. It is one of the basic building blocks used throughout the body to make a variety of chemicals such as enzymes, collagen, amino acids, hormones, neurotransmitters, and much more.
Hydrogen sulphide has a boiling point of -82 degrees Celsius and a melting point of -60 degrees Celsius. There are 2 hydrogen and 1 sulphide molecule. Simple molecule’s which are covalent have lower melting and boiling points as they do not need too much energy to separate the bonds because they are as polarised as water. In hydrogen sulphide the intermolecular forces are known as Dipole-Dipole forces which are less powerful than hydrogen bonding which is in water therefore water has the strongest bond compared to hydrogen chloride and hydrogen sulphide. Water is more electronegative than hydrogen chloride and hydrogen sulphide because there are more molecules in water which are drawn together however in hydrogen sulphide there are less molecules
In addition to taking many human lives, the volcano destroyed every living being – plants and animals – in its path. With the tremors that came after the eruption, there was the possibility of a tsunami, which may have caused even more damage. The eruption, the tremors of the earth, and the possible tsunami destroyed almost everything in the vicinity of the volcano (Gonzalez). Another problem that arises with a volcanic eruption is the volcanic ash. The volcanic ash released from Mount Vesuvius was enough to cover the sunlight, and can be poisonous for humans to inhale. Also, the ash reflects sunlight, which results in the cooling of Earth (Turgeon). While every volcano is hazardous to human life, volcanoes can have a positive effect after the destruction they cause. The ash from volcanoes has many minerals that come from deep under the earth. The ash falls to the ground and mixes with the soil near the volcano. This makes the soil highly concentrated with minerals and very fertile. The fertile soil attracts more people to live in the area around Mount Vesuvius, despite the danger of an eruption (Tilling). On top of the effect it has had on the environment, the Mount Vesuvius eruption has also affected current government
The most common allotrope of sulfur is Octasulfur, which widely exists in nature. It is a soft, odourless, bright-yellow solid. Sulfur is insoluble in water and melts at
The Periodic Table is based around the Atomic Theory. Firstly people believed that everything was made up the four elements Earth, Fire, Wind, and Water. This theory evolved into everything being made up of atoms. Breakthroughs throughout history such as the discoveries of the nucleus, protons, neutrons and electrons have pushed this theory forward to where it is today.
After volcanoes erupt, significant amounts of dangerous and toxic gasses can enter the atmosphere such as sulfur dioxide and carbon dioxide. It is a good thing Japan has an evacuation plan and is ready to clear people of the area because the environment and personal health are going to be affected. These factors of health and pollution where affected in the 2011 during the Fukushima nuclear power plant incident. The Fukushima incident showed that natura...
The writings of some Greek philosophers may be considered to be among the very first chemical theories, such as the theory that all things are composed of air, earth, fire, and water. Each of these were represented by different elements, such as sulfur, salt, mercury, and, ideally, gold. Other ideas held by alchemists were that each of the known elements were represented by heavenly bodies. Gold was earth's representation of the sun, silver for the moon, mercury for the planet Mercury, copper for Venus, iron for Mars, tin for Jupiter, and lead for Saturn.
There are hundreds of flames retardants and they are usually categorized according to their chemical composition. Their chemical composition affects their physical properties such as their color and smell, and their chemical properties
Silicon has an atomic number of 14. It is located in period 3 group 14. Jons Jacob Berzeliusis a chemist that discovered silicon in 1824. He was heating chips of potassium in a silica container. Its boiling point is 5909 degrees. Silicon is the seventh most abundant element in the world. Silicon is made by heating sand with carbon. Silicon is the second most abundant element on the earth’s crust. Silicon is neither a metal nor non-metal.
The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed.
Sulfur is the third most abundant mineral in the human body after calcium and phosphorus and is vital for the proper functioning of the body. Sulfur plays a big role in the oxygenation and detoxification of all cells. Without it, your body simply cannot mobilize and release toxins; toxins will remain embedded in the body’s cells, which will then eventually make us sick.
The Industrial Revolution sparked a new curiosity and need for chemical engineering. In order for certain industries to sustain growth, the production of chemicals became of great importance, especially sulfuric acid. In attempts to improve the process of making this chemical, much time, money and effort was put into it. By this, the slightest savings led to large profits because of the vast quantities of sulfuric acid consumed by industries (Pafko, "Setting Stage").
(Decker) Eruptions then lead to a variety of other hazards such as pyroclastic flows, ash clouds, and mudflows, which is what most likely will affect people nearby the most. Another major volcanic hazard is the release of gasses emitted from fumaroles, which are the openings or small cracks of a volcano. (Myers) For example, an eruption that occurred in 1991 at Mount Pinatubo in the Philippians released a large amount of sulfur dioxide gas, that when mixed with water created a toxic substance called sulfuric acid, which was determined to be one of the factors leading to the damage of the ozone layer. (Myers) Due to the intensity of these hazards, people and the environment suffer from its dangerous
