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
Volcanoes when exploded, can send ash, millions of rock particles and volcanic gas tens of miles into the air. The resulting ash fallout can affect large areas hundreds of miles downwind. Gas pours out of volcanoes in large quantities during almost all eruptions. The gas is made up particularly of steam, but may also include carbon dioxide, nitrogen, sulfur dioxide, and other gases. Most of the steam comes from a volcano's magma, but some steam may also be produced when rising magma heats water in the ground.
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.
Sulfur dioxide is a colorless gas which with a pungent odor. It will become liquid form when under pressure (heat) and will dissolves in water very fast or easily. The primary sources of sulfur dioxide are comes mainly from some activities such as burning of fossil fuel to provide electric power, process of making steel, coal-burning and others. However, it can also be released from the natural volcanic activity or volcanic eruption to the air. This gaseous can easily pose a threat to the living things such as human, animal and plant.
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
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.
Chemically, the asbestos mineral silicate compounds, which means they contain silicon and oxygen atoms in the molecular structure.
Negative ions are created when atoms have a high electronegative charge when they are bonded by covalent bonds to atoms which have a smaller electronegative charge share more electrons compared to the other atom. That is why a tiny negative charge on the atom; is more electronegative and a tiny positive charge which is on the atom ( that it is connected to the molecule) this bond is called a polar covalent bond. The elements electronegativity rises from the top of the groups in the periodic table and from the left to the right across the period in the periodic table. Hydrogen is an atom however it is not as electronegative as oxygen because hydrogen has an electronegativity value of 2.0 on the Pauling scale but oxygen has an electronegativity value of 3. 5 therefore the difference between these two values is 3.5 -2=1.5 which means that the difference in the electronegativity value for hydrogen and oxygen is 1.5. This difference is the reason why water is a polar molecule specifically a polar covalent molecule. The electronegativity value for sulphur is 2.58 on the Pauling scale of electronegativity this suggest that sulphur is also an electronegative molecule Chloride has an electronegativity value of
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.
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.
As science and technology are advancing rapidly, the use of chemicals becomes more and more popular. Chemical reactions are taking place in nature and industries anytime. So far, there are more than a hundred elements has been found by people. And every single element has significant impact on the development of the whole world. Sulfur is an important element existing in nature throughout long history. As sulfur is being widely used, human life has changed tremendously. Sulfur plays a necessary role in daily life. It has great effects on industry, agriculture, medical treatment and many other fields. The property and functions of it is still being discovered by people.
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.
(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
