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 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.

to create the world’s first atomic bomb was a huge project that involved the work of tens of thousands of people and billions of dollars. Most of these resources‚ however‚ did not go into the theory of designing a bomb‚ as design was a relatively small part of the budget; rather‚ the money and manpower were needed to produce weapons-grade plutonium and uranium. Gaseous diffusion was‚ at the time‚ the most efficient way of separating the 235 U and 92 238 U isotopes.1 92 The question of why scientists

The Atomic Café After viewing The Atomic Café‚ I noticed many similarities to the film Radio Bikini that I viewed recently.

The Atomic Bomb: Beneficial or Disastrous? Was dropping the atomic bomb on Hiroshima and Nagasaki at the end of World War II the most affective action that the United States could have taken? In the American eyes it was a good punishment on Japan in response to the Pearl Harbor attacks on December 7‚ 1941.

Atomic energy is energy produced by atoms. The term originated in 1903 when Ernest Rutherford began to speak of the possibility ofatomic energy.[1] The term was popularized by H. G. Wells in the phrase‚ "splitting the atom"‚ devised at a time prior to the discovery of the nucleus. Atomic energy also may refer to: * Nuclear binding energy‚ the energy required to split a nucleus of an atom * Nuclear potential energy‚ the potential energy of the particles inside an atomic nucleus * Nuclear

fossil dating‚ two things come to mind‚ one being‚ “Is that what you’re grandparents do?” (Valls‚ biology class) and two‚ “what is that?”. By using either relative or radioactive dating methods‚ most geologists have the ability to tell how old a single fossil is. As always though‚ we are left with the question of which is better? Delve deeper to understand the comparisons and contrasts of Relative and Radiometric dating‚ as well as further information on both topics individually. Relative Dating Relative
