Homework Answers
positive charge is located at the center and electrons are rotates around the nucleus (positive charge)
hence option 1 is right .

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...

1. In 1911, Ernest Rutherford and his assistants Geiger and Marsden conducted an experiment in which they scattered alpha particles (nuclei of helium atoms) from thin sheets of gold. An alpha particle, having charge +2e and mass 6.64 x 1027kg, is a product of certain radioactive decays. The results of the experiment led Rutherford to the idea that most of the atom's mass is in a very small nucleus, with electrons in orbit around it. (This is the planetary classic...

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...

4. + ㅢ1 points My Notes Ask Your Teacher In 1910 Rutherford performed a classic experiment in which he directed a beam of alpha particles at a thin gold foil. He unexpectedly observed a few of the particles scattered almost directly backward. This result was not consistent with then current models of atomic structure and led Rutherford to propose the existence of a very dense concentration of positive charge at the center of an atom-the atomic nucleus. The alpha particle...

Use the following information to answer the next question. In the Rutherford alpha particle scattering experiment, some alpha particles were deflected coming straight back from the gold foil. When an alpha particle is emitted by the radium sample, it has a kinetic energy of 1.0 x 10-22 J. The electric potential energy of a charged particle in a radial electric field is modelled as kq192 Ер r Numerical Response 2. The maximum acceleration of an alpha particle at its closest...
