Introduction to Rutherford Alpha Particle
The Phenomenon of radiation has puzzled scientists for decades. The study of radiation gave the scientists an insight into the otherwise abstruse inner structure of the atom.Lord Ernest Rutherford was one such practical physicist who was heading the search into the then unknown atom.
Before Rutherford's heroics with the alpha particle, Lea Thomson had promulgated the idea of "PLUM CAKE" Model in which atom is considered as a positive charged ball in which there are negative charges placed. Having problem with Specific Heat Ratio keep reading my upcoming posts, i will try to help you.
Ruherford's Alpha Particle Scattering Experiment:
In a highly practical experiment, Rutherford designed a mechanism to bombard a very thin gold foil with high speed Alpha Particles. Assuming the accepted atomic models, a majority of the alpha particles were to collide with the gold atoms and get scattered. But the results seemed confound everyone.
Instead of going and hitting the gold atoms, almost all the alpha particles went straight through and hit the flouroscent screen beyond the gold foil. A very small portion though had either been reflected back or scattered by an angle as if they hit a massive particle.
It was as if "Shells had been fired at a thin curtain and some bounced back, while most went through."
Looking out for more help on Projectile Motion Physics Problems in physics by visiting listed websites.
Rutherford Aloha Particle Scattering Interpretation- Planetary Model of the Atom
The results of this experiments led to the development of a new model of the atom called the "Planetary Model".
Accordingly the entire positive charge consisting of massive protons is concerntrated in the nucleus, which is at the centre of the atom and is highly dense. It contributes to almost the entire mass of the atoms. The extremely light electrons on the other hand revolve arond this nucleus following circular paths called orbits in empty space sourrounding the atom.
This was the first model that actully resembled the present day accpted model of the atom. Rutherford's experiment later led to the Bohr Model (named for Neils Bohr) and later the modern wave-mechanical model of the atom.
