On August 6‚ 1945‚ the United States of America dropped an atomic bomb on Hiroshima‚ Japan. The United States was justified to do this because of the unprovoked attack and bombing of Pearl Harbor‚ Hawaii‚ which occurred three years prior to the bombing of Hiroshima‚ and it was necessary to stop the war because it saved thousands of American lives. Until then‚ the fight had never been on United States soil. The innocent civilians of Japan did not have to worry about being killed on their land until

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

ATOMIC PHYSICS The nuclear atom All matter is made up of atoms which consist of a central nucleus‚ surrounded by electrons. Inside the nucleus are protons and neutrons. Particle Relative mass Charge Location Proton 1840 + Nucleus Neutron 1840 0 Nucleus Electron 1 - Outside nucleus Proton or atomic number (Z) This is the total number of protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon

of six individuals that survived the atomic bomb of 1945. Without this book one could not truly determine if what we did to the Japanese was justified or not. We can also look at the way the journalism shapes our out look on things. This is why we always need to look at all the facts before we truly make up our mind on a subject. The book Hiroshima was a great story that was told through a third party perspective in order to explain the horrors of the atomic bomb. A few of the individuals duplicated

multiple scientists that contributed to the creation of the first Atomic Theory: Democritus‚ Antoine Lavoisier‚ Joseph Proust‚ and John Dalton. Dalton took the information that he had taken from the three scientists prior to him and put everything into one theory. The Atomic Theory is the most well-known and accurate theory we know right now. Later on in history‚ more scientists came to contribute to the understanding of the Atomic Structure. These scientists included: Sir J.J. Thomson‚ Robert Millikan

DEVELOPMENT OF THE ATOMIC THEORY Part A: HISTORY * 1869: Mendeleev formulated the Table of the Elements - listing them by their atomic weight and grouping them with similar characteristics. * 1897: JJ Thomson discovered electron and isotopes‚ and invented the mass spectrometer. * 1898: Marie Curie discovered and isolated radium‚ a new element which unprompted disintegrated into other elements. This proved that the atoms of one element at least were not indivisible. * 1911: Ernest

The History of Atomic Theory Atomos: Not to Be Cut The atomic model has changed throughout the centuries starting in 400 BC‚ when it looked like a billiard ball. Democritus: 400 BC The question: Can matter be divided into smaller particles? Or can it be infinitely divided? Matter can be divided into the smallest piece‚he named it “atomos”: not to be cut. Said that atoms were small‚ hard particles that were all made of the same material but were different shapes and sizes. Atoms were

The Progress of the Atomic structure Different theories about the atomic structure were introduced over time. These theories changed as a result of development of different experiments. Leucippus was the first to introduce the theory of atomism‚ however he didn’t write about his theories in detail. However‚ Democritus‚ his student wrote about the theory of atoms in detail. He theorised that everything was composed of atoms and that atoms are solid and indestructible. He also had a theory that
