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 Rutherford established that the nucleus was very dense‚ very small and positively charged. He also assumed that the electrons were located outside the nucleus. * 1922: Niels Bohr

the years of 1905-10. It is defined as energy released by reactions within atomic nuclei‚ as in nuclear fission or fusion. Now a days it is referred to Nuclear energy. Nuclear power uses fission (splitting atom nuclei) to produce energy. Atom nuclei is also none as the nucleus (center of the atom). Around 6% of the world’s energy and 14% of the world’s electricity is produced by nuclear power. There are over 400 nuclear power reactors in use around the world. The largest producers of nuclear power

NUCLEAR ENERGY Nuclear energy is the energy contained in the centre ‚ or nucleus of an atom. The nucleus is the most powerful source of energy that exist. Nuclear energy is use in scientific research and in medicine treatments. It powers satellites and submarines‚ and it is used to produce electricity. People have also put nuclear energy to destructive uses through the creation of weapons.1 Nuclear energy also called ATOMIC ENERGY‚ energy

Historical Development of Atomic Structure Yazan Fahmawi Sept. 30‚ 1995 T3 IBS Chemistry Ms. Redman The idea behind the "atom" goes back to the Ancient Greek society‚ where scientists believed that all matter was made of smaller‚ more fundamental particles called elements. They called these particles atoms‚ meaning "not divisible." Then came the chemists and physicists of the 16th and 17th centuries who discovered various formulae of various salts and water‚ hence discovering the idea of a molecule

consequences; a child curious about the kitchen stove is bound to get burned. This is exactly what Kurt Vonnegut demonstrates in Cat’s Cradle with the example of ice-nine‚ which is developed by the fictional creator of the atom bomb‚ Felix Hoenikker. It is symbolic of the atom bomb in that it has the power to end human life. Hoenikker is obviously an exceedingly smart man; however‚ it can be inferred from his inventions that he does not always consider the negative consequences of his new discoveries

Sadako was a Japanese girl. When the atom bomb dropped in Japan‚ she was only a little baby. Her grandma was killed by the bombing. Today is a memorial day; the family did the tradition way to remember her‚ which is to set free a white drove. The new school year has begun; Sadako was excited to join the track team. But she kept feeling dizzy and was sent to the hospital. The doctor told her that she had Leukemia. She can’t believe it‚ that means that she has to stay in the hospital and can’t join

– much like a fossil-fueled power plant – water is turned into steam‚ which in turn drives turbine generators to produce electricity. The difference is the source of heat. At nuclear power plants‚ the heat to make the steam is created when uranium atoms split – called fission. What is the process that occurs during a nuclear chain reaction? Nuclear Chain Reactions. A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus

Max Karl Ernst Ludwig Planck was born in Kiel‚ Germany on April 23‚ 1858 (Foundation‚ 2014). He was awarded the Nobel Peace Prize in 1918 and developed what would come to be known as “Planck’s Constant” in quantum theory. During his collegiate years he studied under Gustav Kirchoff‚ who developed Kirchoff’s Law for current and voltages. He suffered a personal tragedy when one of his sons was killed for his participation in an assassination attempt against Adolf Hitler in 1944. Planck’s earliest
