The element Neon has a symbol of Ne. Neon’s atomic number is 10, which is the same as its protons. The protons and electrons are always the same. That means the electrons are 10 and put into two different rings. On the first ring there will be 2 electrons and on the second ring there is 8 electrons. That gives them a total of 10 electrons. Along with atomic number, protons, and electrons there is a atomic mass which is 20.1797.
Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of Krypton. Like krypton, neon was discovered through the study of liquefied air. Although neon is the fourth most abundant element in the universe, only 0.0018% of the earth’s atmosphere is made up of neon. Sir William Ramsay and Morris M. Travers discovered this element in 1989 after Krypton. Neon got its name from the Greek word “neos,” which means new because it was newly discovered by Sir WIlliam Ramsay and one of his students Morris M.

The gas is placed in glass tubes and an electric current is sent through the gas. When that occurs, neon enters a plasma state and glows orange-red. Neon is the tenth element of the periodic table and the second of the noble gases. The element is incredibly non-reactive because of its electron configuration. They use this noble gas for Neon signs, TV tubes, Cryogenics, and Lasers. On loss of containment this liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when in confined areas. This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue. At low oxygen concentrations, unconsciousness and death may occur in seconds without
One must look to see which element has both violet and orange spectra lines. It is shown that the element Cesium is the only element that has both violet and orange spectra lines. 2. Describe two different approaches to exciting the electrons that exist in elements. Offer a specific reason why scientists use different approaches to excite the electrons of different elements.
SVN 3M The Nitrogen Cycle Name: Isabelle Rowe Go to the following website: http://nortonbooks.com/college/biology/animations/ch38a02.htm 1. What are the 2 forms of usable nitrogen? The two forms of usable of nitrogen are ammonium and nitrates. 2.
Atoms are made up of three basic components: Protons, Neutrons, and Electrons. The proton particle carries a positive charge while the neutrons carry no charge(neutral). When combined, the protons and neutrons make up the central part of the atom also known as the nucleus. The electrons carry a negative charge and its role is to circle around the nucleus. Each atom also has a unique number of both protons and neutrons that is known as the atomic number.
Where as, electrons are negatively charged(Doc.3).The neutron is the dense middle of the atom(Doc.3). The protons and neutrons in the atom are in the nucleus(Doc.3). However, the electrons preside in electron clouds outside the nucleus(Doc.3). To sum up, an atom is a small structure that defines what an element is and
Electrons are a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. Inside the dense nucleus, are protons and neutrons (Doc. 2). Protons are a stable subatomic particle with a positive charge that is the opposite of an electron and occurs in all atomic nuclei. Lastly is the neutron. It is a stable subatomic particle that has no charge and has nearly the same amount of mass as a proton.
Who discovered it? How did they discover it? It was not Thomas Jefferson and it was not George Washington, so who was it? On the 17th of January 1706, a man by the name of Benjamin Franklin was born.
Wilhelm Roentgen was a German physicist who discovered x-rays. Not only was his discover useful for his time period, but for ours as well. Wilhelm Conrad Roentgen was born March 27, 1845 in Remscheid, Germany. At the age of 3, Roentgen attended the Institute of Martinus Herman van Doorn. Roentgen also attended Ambachtsschool in 1862, where he was later expelled due to an altercation with a teacher.
Tonya Gusevik HIST102 Dr. Lupo August 16, 2015 The Manhattan Project The Manhattan Project is a short history of the beginning of the Atomic Bomb program during World War II. Nuclear research all started when the Japanese bombed Pearl Harbor, and the United States entered into World War II. Scientific development began in the years prior to the war. The program started in 1939 and grew to employ more than 130,000 people.
He also fluently spoke six languages. Back then, that was a lot of knowledge, especially for a kid. He also discovered 10 very important gases: Nitric Oxide, Nitrous Oxide, Nitrogen Dioxide (Laughing Gas), Hydrogen Chloride, Ammonia, Sulfur Dioxide, Silicon Tetrafluoride, Nitrogen, Carbon Monoxide, and last but not least, Oxygen. This fantastic work rewarded him with a Copley Medal.
Franklin discovered that an excess of electrical fluid was a positive charge, and a shortage of electrical fluid led to a negative charge. He was also the first to say an electrical charge cannot be created, it can only be collected. In 1751 Franklin published a book called Experiments and Observations on Electricity. This book was widely read in Britain and Europe. ( Benjamin Franklin Bio)
Encomium Essay Someone that has inspired me to be who I am to this day is my mom Mirna Castellon and I’m going to explain why I praise her for everything she has done for me. A little background on my mom she’s is original from San Salvador, El Salvador. At the time San Salvador where she lived was a really poor place and the Salvadoran civil war was happening also well. My mom was raised during the civil war and she became a strong woman from this experienced that happen to her.
The effect was named after physicist Pierre-Victor Auger, who “discovered” it in 1925. While Lise Meitner uncovered this effect in 1923 two previous years before Pierre-Victor Auger. Later in 1926 Meitner accepted a position at the University of Berlin, becoming the first woman in Germany to become a full professor of
“Upon checking a frozen, compressed sample of tetrafluoroethylene, he and his associates discovered that the sample had polymerized spontaneously into a white, waxy solid to form polytetrafluoroethylene.” (History of Teflon, year) Polytetrafluoroethylene, PTFE, more commonly known as Teflon was not invented, meaning it was made for a reason, but discovered by accident by Dr. Roy Plunkett in 1938. Teflon is one of the many serendipitous discoveries that have become very helpful and used frequently in our society today. In the past, Teflon was used to coat pipefittings to make them leak proof to prevent radioactive materials from escaping in World War II. Currently, it is most commonly used as a non-stick coating on cookware and to make dirt

History of the Technology The first Nuclear fusion theory was proposed in 1920, by Arthur Eddington. He proposed that the energy release by the fusion of small nuclei would provide large amounts of energy.
