Rutherford's Experiment
A stream of alpha particles (much like a stream of tiny bullets) was directed at a thin foil of gold atoms and a detector arranged to surround the sample completely, except for a small hole for entry of the particles. The foil was several thousands of atoms thick. ..

Structure of the Atom - Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experime..
Rutherford's nuclear model
On the basis of the scattering experiment, Rutherford described the structure of the atom as: An atom consists of a positively charged nucleus surrounded by electrons that move around it. The positive charge of the nucleus is due to the..
Structure of Atom Summary
Summary - Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J. Thomson led to the discovery of electron. Goldstein's experiment with the discharge tube having a perforated cathode led ..
Models of Atom - J.J Thomson's and Rutherford's Models
After the discovery of electrons and protons it was necessary to know how these particles are arranged within the atom. Various scientists tried to describe this structure and after subsequent improvements through experiments, the structure of an atom..

Atoms and Nuclei Summary
Summary - Dalton had postulated that matter is made up of atoms, which are indivisible. Thomson was the first to suggest a structure for an atom. According to him, an atom is a positively charged sphere of radius=10 - 1 0 m in which the mass and the positive ..

We had a very good debate about the pieces of an equation in standard form. Wonderful session. I enjoyed the session.
It was fun! It showed me a easier way to do multiplication with bigger numbers,Thank you all - Christian
Very informational yet simple and easy to comprehend. Tutor Vista is helping me a lot.
