Rubidium is a chemical element that was discovered in 1861 by Robert Bunsen and Gustav Kirchhoff‚ in Heidelberg‚ Germany through a scientific process of flame spectroscopy. During the process‚ Kirchhoff and Heidelberg noticed bright red lines in its emission spectrum which caused them to choose the name Rubidium derived from the Latin word rubidus‚ meaning "deep red". Rubidium is a chemical element with symbol Rb and atomic number 37 and an atomic mass of 85.4678. Rubidium is a soft‚ silvery-white

Trinitrotoluene‚ TNT‚ or 2‚4‚6-trinitrotoluene‚ is a nitro chemical compound with the formula C₆H₂(NO₂)₃CH₃. TNT is a yellow-colored solid and contains in its structure three NO2 groups and one –CH3 group all bonded to carbon atoms on the aromatic ring (Juhasz and Naidu 2007‚ Pichtel 2012). Oxygen and nitrogen are the two highly electronegative elements where oxygen possesses the highest electro-negativity. Subsequently‚ the polarized N–O bonds within the nitro groups makes them easily reducible

Dynamite was invented by Alfred Nobel in order to develop the industry of getting minerals and digging tunnels; however‚ Dynamite is now widely used in military purpose. Similarly‚ nuclear energy is undoubtedly a powerful source of energy compared to other conventional fuels such as coal‚ oil and gas. However‚ nuclear energy also has a lot of disadvantages‚ such as nuclear wastes‚ nuclear plant accidents and nuclear weapons. So before widely use this technology‚ both pros and cons should be taken

Plutonium Contamination and Radiation Effects In Kristen Iversen ’s book‚ Full Body Burden‚ she talks about the causes and effects of the plutonium contamination and radiation effects. There are many effects caused by plutonium contamination and radiation exposure. There are many different types of cancer caused by the exposure. There are three main cancers discussed in her book. They include bone or lung cancer‚ brain cancer‚ and leukemia. Bone and lung cancer is a main effect of plutonium

The Radioactive Boy Scout Silverstein‚ Ken The Radioactive Boy Scout: The Frightening True Story of a Whiz Kid and His Homemade Nuclear Reactor (2005) . I chose this book on many accounts not the least of those being that I heard everyone talking about it in class. I also was intrigued about this book based upon the synopsis that I read in wikipedia. Which explained it well enough to catch my eye and investigate the story to see if I liked which ultimately I had a fine time reading it. I also enjoy

I found out from this experiment that half-life means just what it sounds like. After each cycle of half-life‚ the number of coins left was about half. Each coin represents an atom and just like in nature the half-life of decay is half depending what the element’s half-life is. If each of the scatter test was 10 years‚ the element we are testing would have a half-life of 10 years. The amount of time for a half-life depends on the elements‚ and how tightly the atoms are packed together. Some other

In the video Hands-On Science with Squishy Circuits and the articles Energy Story and “Conducting Solutions.” They all had something to do with electricity. They all had a purpose as to what it was trying to teach you. In the next few paragraphs I will explain what I think the purposes are of these articles and this videos. The purpose of Energy Story is to teach people about energy and help them figure out what kind of particles and in what ways make electricity possible. In the article the

Nuclear energy in itself isn’t bad. In fact‚ nuclear energy is considered one of the most environmentally friendly source of energy because contrary to traditional sources like coal‚ nuclear energy produces less carbon emissions when producing electricity. Although Latvia doesn’t possess any nuclear power plant‚ Latvia imports nuclear energy to supply the demand of its citizens’ electrical consumption. The dangerous thing about nuclear energy is when it is turned to a weapon. Latvia‚ being

I am going to discuss the modern concept of the atom. I am going to give a brief history of the atomic model including Thomson’s atom‚ Rutherford’s atom‚ Bohr’s atom‚ and Schrödinger’s atom. I am going to include a diagram for each of these models. In 1897 physicist‚ J.J. Thomson‚ shortly after discovering electrons‚ proposed his Plum-Pudding model of the atom. He based this model on the two facts that he knew at the time: 1. atoms contain small negatively charged particles called electrons
