For each of the following scientist that contributed to the early modern atomic theory, write a paragraph on their contribution and how their contribution changed Dalton’s atomic theory: Rutherford, Thomson, Millikan, Chadwick 2. For each of the following experiments, write a paragraph on how it contributed to the understanding of the structure of the atom: Rutherford Cathode Ray Tube, Millikan Oil Drop Experiment, Rutherford Gold Foil Experiment, and Chadwick Neutron Experiment.

In the early part of the 20th century, Sir Joseph J. Thomson (discoverer of the electron) proposed a "plum pudding" model of the atom. He believed that the positive charge of the atom was spread out like a pudding and that the negative charges (electrons) were embedded in the pudding like plums. His student Ernest Rutherford performed an experiment in 1911 that disproved the plum pudding model. Rutherford fired a beam of alpha particles (helium nuclei) at a thin metal...

In a fictitious world the Thomson cathode ray experiments found the electron charge to mass ratio to be 9.25×105 C/g. A series of oil drops in the Milikan oil drop experiment were found to have excess charges of 3.73×10-19 C, 4.66×10-19 C and 2.80×10-19 C. What could be the mass of an electron? 1.01×10-25 grams 2.80×10-19 grams 3.73×10-19 grams 5.04×10-25 grams 4.03×10-25 grams

Determine how many protons, neutrons, and electrons a given atom (or ion) has, given its symbol, atomic number, and mass number (and vice versa) . Describe the relative mass, charge, and location of the three basic particles in the atom (a, B, Y) 4. State what isotope serves as the current standard for the atomic mass scale. 5.

Imagine an alternate reality. The Thomson cathode ray experiments arrived at a charge to mass ratio, 8.51×106 C/g for the electron. If when Milikan performed the oil drop experiment he found that a series of droplets had excess charges of 3.11×10-19 C, 1.56×10-19 C and 2.08×10-19 C, what could be the mass of an electron?

In the Rutherford Gold Foil experiment, alpha particles (with a charge of 2e and a mass of 6.645x1027 kg) were shot directly at a thin sheet of gold with ht t but of the time t sometimes they would bounce directly back. The alpha particle would only bounce back when its path was aimed directly at a gold nucleus (otherwise it would pass through the empty space between nucle atom (rather than spread out even through the atom What is...

In the Rutherford Gold Foil experiment, alpha particles (with a charge of 2e and a mass of 6.645×10-27 kg) were shot directly at a thin sheet of gold with a speed of 1.017×107 m/s from very far away. They found that most of the time the alpha particles traveled straight through the thin sheet, but sometimes they would bounce directly back. The alpha particle would only bounce back when its path was aimed directly at a gold nucleus (otherwise it...
