INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

The End of World War II The United States Decision to drop the Atomic bomb has been a controversial topic since the day the first bomb was dropped August 6‚ 1945. President Harry Truman made the ultimate decision to use the atomic bomb‚ to him it was a clear decision that this would end the war with America’s most hated enemy: Japan (Nathan‚ 2012). There had been thousandths of bloody deaths up to-this-point in the war‚ Japan was destroyed‚ they had just about nothing‚ their country was in starvation

Atomic weapons are similar to poison gas – both are barbaric.The U.S.A. should not shock the world with such a weapon. What we have to understand is that current bombing campaign against Japan has brought the country just about to its knees. The atomic bomb will

The dropping of the atomic bombs showed the world that the United States was a force to be reckoned with‚ and established it as a commanding force. The US had not been a part of the League of Nations‚ and had less global participation and influence in years past. At the end

ATOMIC THEORIES AND HISTORY * Democritus (Greek) - “atomus” meaning indivicible * Indivisible particles called atoms * John Dalton – MODERN ATOMIC THEORY: 1. All matter is made of tiny‚ indestructible particles called atoms (Democritus) 2. All atoms of a given element are identical (not accepted today bc isotopes) 3. Atoms are neither created nor destroyed in chemical reactions (Lavoisier) 4. Atoms of different elements form compounds in whole number ratios (Proust)

Composition II “You Have Atomic Bombs‚ but We Have Suicide Bombers” In Rohde’s article we learn of his experience as a hostage in Afghanistan and Pakistan. He explains the Islamic cultures and values‚ but shows us his view on them. Their cultures have some similarities‚ but more differences. We both have religions‚ but Americans approach their religion differently and less violently. America’s whole reality and country differs greatly from the Taliban’s society. The Taliban’s reality differs

1.1 The atoms‚ during bond formation‚ may lose or gain electrons (valence electrons) in order to achieve a stable state‚ or technically speaking‚ a stable electron configuration. Usually metal atoms lose electrons and non-metals gain electrons in order to achieve electron stability. When dealing with bond formation (Ionic bonding for example) we need to analyse the outer shell of the atom. Metals usually present 1‚ 2 or 3 electrons in their outer shell therefore they have to give them away to achieve
