Let us know your assignment type and we'll make sure to get you exactly the kind of answer you need. No prior knowledge had prepared them for this discovery. The positive and negative charges of protons and electrons are equal in magnitude, they cancel the effect of each other. Hence, when the incident alpha particle came very close to the positive mass in the centre of the atom, it would repel leading to a deflection. The experiment which proved the existence of a nucleus in the atom. Almost all the alpha particles did pass through the foil. Why are alpha particles not deflected by the nucleus? What was the thickness of gold foil used in Rutherfords experiment? What was the basic premise of Gold Foil experiment that was conducted by Ernest Rutherford and what did it overwhelmingly prove? How does Rutherford's model of the atom explain why some of the alpha particles directed at the gold foil were deflected straight back toward the source? Alpha particles are positive, so they might be repelled by any areas of positive charge inside the gold atoms. Some were even redirected back toward the source. by losing one electron it gains stability hence its valency is 1. He observed that more than 99% of these particles were able to go straight and pass through the gold atoms. The plumb pudding on the left, assumes that the neutrality of the atoms is due to the mixing of positive and negative charges, as in the image. Very few of the alpha particles (one or two) even bounced backwards after hitting the gold foil.

Rutherford's model proved to be an important step towards a full understanding of the atom. Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus.They are generally produced in the process of alpha decay, but may also be produced in other ways.Alpha particles are named after the first letter in the Greek alphabet, .The symbol for the alpha particle is or 2+. Rutherford's atomic model became known as the nuclear model. The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. The particles that were deflected to the sides were deflated by a passing electron that moved the alpha particle out of the way. Short Answer. gold atoms were quite large and so alpha particles could fit . The direction of deflection which can be determined by Fleming's left hand rule demonstrates that they must be positively charged. I think that the reason behind it is that the speed of the electrons travelling in orbits did not cause any obstacle in the travelling path of the alpha particles. A small fraction of the alpha particles were deflected (scattered) through a large angle, indicating such a strong electric field within the atom that the positive charge must be concentrated in a small central corea core that is massive as well as small because the rebounding alpha particles showed no appreciable loss of kinetic energy. Beta particles are fast-moving electrons with a very low mass and so have a high charge to mass density. What caused a large deflection of alpha particles in Rutherford's experiment? of neutrons. On the right the Rutherford experiment showed that the positive charges were concentrated in the center, leaving the negative on the periphery. In 1911, Rutherford and coworkers Hans Geiger and Ernest Marsden initiated a series of groundbreaking experiments that would completely change the accepted model of the atom. Separation of Mixtures using Sublimation and Magnets. We see that as the kinetic energy E increases, the deflection angle decreases. These are the reflected rays. The symmetrical distribution of charge would allow all the particles to pass through with no deflection. still, there was no clear model that defines atoms, therefore in 1909, Ernest Rutherford, a British scientist conducted an experiment and based on the experiment he observed and proposed the atomic structure of elements and Rutherford Atomic Model.
