exposed to Anthrax there was a HAZMAT plan in place depending on our location. Weapons of mass destruction have been around for many years like the atomic bomb that we dropped on Japan years ago. This caused an enormous shock wave spreading radioactive isotopes for miles. Just recently there was the nuclear power plant in Japan that leaked after an earthquake started a tidal wave. It was weeks before they could see what the severity and the damage to the public after the nuclear leak. Chemical agents

Austin Dobrzynski Chem 1 10/11/14 Copper Ch. 3 Isotope Paper Copper In humans‚ copper is essential to the proper functioning of organs and metabolic processes. The human body has a complex homeostatic mechanism that lets us supply copper‚ while eliminating excess copper whenever this occurs. The dietary standards for copper have been set by various health agencies around the world. Standards adopted by some nations recommend different copper intake levels for adults

JOHN DALTON Five main points of Dalton’s atomic theory 1. Elements are made of extremely small particles called atoms. 2. Atoms of a given element are identical in size‚ mass‚ and other properties; atoms of different elements differ in size‚ mass‚ and other properties. 3. Atoms cannot be subdivided‚ created‚ or destroyed. 4. Atoms of different elements combine in simple whole-number ratios to form chemical compounds. 5. In chemical reactions‚ atoms are combined‚ separated‚ or

That happens because of isotopes. An atom that is missing a neutron or has an extra neutron is called an isotope. They are still the same element; however‚ they are just a little different from every other atom of the same element. Most of the carbon atoms in the universe are Carbon-12‚ with 6 neutrons. A small percentage of carbon atoms are Carbon-13‚ with 7 neutrons‚ and an even smaller percentage are Carbon-14 and have 8 neutrons. Carbon-13 and Carbon-14 are isotopes of carbon. Atomic mass

141 Chapter 3 Stable Isotope Fractionation In 1913‚ Sir J.J. Thomson found that the element neon has two different kinds of atoms with atomic weights of 20 and 22‚ respectively. This was the first experimental proof of a hypothesis by F. Soddy that different atoms might occupy the same place in the Periodic Table. Soddy named these atoms isotopes‚ which in Greek means equal places (Soddy‚ 1913). For his experiments‚ Thomson used a so-called ‘positive ray apparatus’‚ a predecessor of today’s mass

Purpose The purpose of the “Beanium” lab was to determine the average atomic mass of three different isotopes of beanium. During the lab beans were counted to determine mass of the sum of the beans. Each type of bean were weighed separately and then averaged together to determine the average atomic mass of beanium. Materials and Hazards Analytical balance‚ coffee filter‚ pencil‚ paper‚ cup‚ American beans‚ Nigerian beans‚ Mexican beans‚ calculator‚ and paper. Raw Data Bean Total Mass w/ Cup Number

spectrometer has been a universal research tool‚ mostly involved in comparing the masses of atoms. Since the invention of this tool about 100 years ago‚ the mass spectrometer has been responsible for the description of molecular structure‚ the detection of isotopes‚ the classification of atomic weights and more! The mass spectrometer has been vital to chemistry‚ and will continue to do so for more years to come. The history of the mass spectrometer starts with a man named Sir Joseph John Thompson. Thompson

In the song “Radioactive” by Imagine dragons is about a time in prison with hard physical labor. The song has more than just one meaning‚ one is the hard physical labor of a prisoner and the second one is an uprising getting back into reality from prison. At the beginning stanza of the song the lead vocalist Dan Reynolds sing “ I wipe my brow and sweat my rust” (Line 6) which means very hard physical labor and abuse from instructions or other personals. This line means a lot to people who have been
