speak)‚ there is much information regarding its atomic buildup. Every element’s atoms are composed of three main subatomic particles: neutrons‚ electrons and protons. Located in the atom’s nucleus‚ protons and neutrons are referred to as nucleons. The electrons rest outside of the nucleus at various energy levels (orbitals). Most of an atom’s mass comes from its very small nucleus‚ whose protons and neutrons each have a mass of approximately 1 u (atomic mass units). Electrons‚ on the other hand‚ have

Chemistry Atomic Structure: The Electron A myriad of trends occur on the periodic table‚ whether it is defined through the size of the atoms or the first ionization energy that may occur‚ many other trends can be found simply looking horizontally or vertically on to the table. As you look from left to right you can see that the reactivity of the elements increase‚ this is due to the number of electrons increasing on the shell. This also once you go down the table; the shells become further and

Route that never broke the business capital of India was once again rocked by serial blasts on July 11‚ 2006. There were 8 explosions in 8 local trains between 6.20 and 6.35 p.m. resulting in 190 causalities and more than 600 injured. After the 1993 serial blasts this was the severest terrorist attack in the country. There were eight explosions within 12 minutes between 6.21 and 6.33 in the local trains and railway stations. The first blast occurred at Kher o a train bound for Boriwali fram Churchgate

The world changed in 1945 when the atomic bomb was dropped on Japan‚ many people have debated whether or not this was necessary. The United States atomic bombing of Japan was justified. The Japanese would not have given up if the United States had not dropped the two atomic bombs. The Japanese code to encrypt messages was called the Purple Code‚ by this time in the war the United States had long broken the Purple Code and in their “Secret” messages. They said that they were not going to surrender

The Evolution of the Atomic Theory Rob Congrove B4 10/23/00 The five atomic theorys of the past two centuries represent the sudden advancement of science in modern times. Beginning with a basic theory on the behavior of atoms to the current model‚ some changes have been made‚ and some ideas are still the same. Ancient Greek philosophers believed that everything was made up of invisible particles called atmos. Since then the theory of atoms did not progress until 1803. John

goal of ending a war. The USA will do whatever they can to protect their people like inventing the atomic bomb which they used to end World War 2. To drop the atomic bombs to stop the war they used the planes “Enola Gay” and “Bockscar”.(atomcentral) The first bomb was “Little Boy” was carried by Enola Gay while “Fat Man” was carried by Bockscar.(atomcentral) Little Boy was the first of the bombs and was dropped on Hiroshima then Fat Man on Nagasaki.(atomcentral) The pilots of the planes were Paul

This question has been floating around the air for years now‚ The first bomb was dropped on the city of Hiroshima‚ Japan in 1945 of August 6. This devastating bomb killed around 135‚00. There was also a second bomb that hit Nagasaki on August 9th that killed approximately 50‚000. But the question remained was this necessary? In my opinion YES! Dropping the bomb was very necessary‚ it was also reasonable considering the fact that US lost a total of more than 418‚000 both military and innocent civilians

Chemistry of Bath Bombs Date: 16th May 2014 Introduction – When sodium bicarbonate and citric acid mix in water they dissolve‚ the sodium bicarbonate reacts with the citric acid to form sodium citrate and carbon dioxide. The carbon dioxide then bubbles out as a gas‚ which makes the bath bomb break up‚ in this experiment 3 tests will be conducted in order to find the correct ratio of bicarbonate soda and citric acid to create the

Determination of Trace Amount of Copper and Zinc in an Aqueous Solution by Atomic Absorbance Spectroscopy Abstract: The purpose of this experiment is to analyze a sample containing copper and zinc in trace amounts‚ where standard addition method was used and the instrument used is the atomic absorbance spectroscopy. The amount of copper obtained was 0.569 ppm ± 0.015 and for zinc we obtained 0.42 ppm ± 0.0027. Introduction: This method implies the excitation of particles in the solution sample
