Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he

Of all of the many scientists who played a major role in the formation of the atomic theory‚ it is believed that Dalton‚ Rutherford‚ Thompson‚ Bohr‚ and Planck are the five most influential. The research of this theory has gone on for many years and each and every one of them have brought us closer to our current understanding of the atom today. Each one of them played a special role in the development process of the atom and most importantly‚ they all reflected on one another. Many influential scientists

The Atomic and Nuclear Structure of an Atom The atom has three main components the protons‚ neutrons‚ and electrons. The protons and neutrons make up the nucleus‚ while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge‚ and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative‚ positive or neutral. These are called

Further progress in the understanding of atoms did not occur until very famous scientist created the atomic theory. Here are some scientists who changed the way we learn about the atom‚ and the atomic nature of all life. Ernest Rutherford. Ernest Rutherford was another scientist that changed the atomic model. Rutherford was studding physics up until his junior

Short Notes On Atomic Structure * Atom is the smallest particle of an element- All 117 elements has atoms * Bohr model: - Planetary model (see Figure 1 below) 1. Sun (proton & neutron= nucleus) 2. Planets (electrons) 3. Orbit (shell) Figure 1: Bohr model * Each type of atoms has a certain number of electrons and protons that differentiate it from the atoms of other elements Example: 1 proton 1 electron= Hydrogen (1 type elements) 2

Thank God for the Atomic Bomb In Paul Russell’s passage from Thank God for the Atomic Bomb‚ he describes how the atomic bombings of Hiroshima and Nagasaki were fully necessary. Russell agrees with President Truman’s decision to drop the atomic bombs because of the logical reasons. He gives examples that compare to the overall effect to America‚ and the positive things that happen to America such as the fact that the war would be over. I agree with Fussell’s opinion because the atomic bomb solved many
Premium Atomic bombings of Hiroshima and Nagasaki World War II Nuclear weapon
Were the atomic bombings in Hiroshima and Nagasaki necessary to save allied lives and to end Japan’s threat to world peace? Did the resulting loss of life cost more than a deadly invasion of the Japanese mainland? In August 1945‚ the first dropping of atomic bombs in civilian areas of Japan killed hundreds of thousands of innocent people. Immediately following those bombings‚ Japan surrendered to the United States. The following essay summarizes the defense of the atomic bomb and its use‚ the arguments
Premium World War II Atomic bombings of Hiroshima and Nagasaki Nuclear weapon
On August 6‚ 1945 the United States dropped the first atomic bomb ever on the Japanese city of Hiroshima. They also dropped a second bomb three days later‚which eventually ended World War ll. Was it the right thing to do? It created many controversial dilemmas on whether it was right or not. There are many people who oppose the use of the atomic bombs; though there are some that believe it was a necessity in ending the war. I think that there could have been other ways to end World War ll.

WAS THE ATOMIC BOMBINGS OF HIROSHIMA AND NAGASAKI JUSTIFIED? A bomb which was equal to 13‚000 tonnes of highly-explosive bombs‚ used to make the Japanese surrender‚ but also killing many lives‚ cannot be justified. When the highly-explosive bombs were dropped in Dresden‚ everyone had thought of this as very affective. But imagine how bad the atomic bomb would be‚ which could destroy a city only just by its radiation‚ let alone the actual explosion. President Truman of America made a decision of
