What happened to the alpha particles when they hit the gold foil?
Alpha particles only have 2 protons, so the positive charge is not strong enough to attract the electrons in the gold atom. It might have definitely interacted, with the electrons “pulling” them toward themselves, which result in a tiny force which pushed the alpha particles straight through the atom and out of it.
What is his explanation to the alpha particles that bounce back?
Alpha backscattering on nucleus Rutherford observed the backward bounce of some alpha particles as projectiles sent on the atoms of a thin gold foil. He interpreted this rebound as the “backscatter” of a light nucleus (alpha particle) on the heavy nucleus of a gold atom.
Why do most alpha particles fired through a piece of gold foil emerge almost Undeflected?
Why do most alpha particles fired through a piece of gold foil emerge almost undeflected? The massive alpha particles blast through the majority of the space in the gold that is occupied by low mass electrons. The mass of the atom is concentrated in a positively charged core.
What do you notice about the paths of most of the alpha particles?
What do you notice about the paths of most of the alpha particles? Most of the particles stay on a straight path but the ones that hit the nucleus bounce off and continue on a slight angle. 2. Increase the number of protons to 60.
What path do the particles take most often when they hit the foil?
Most of the alpha particles passed straight through the gold foil as though it wasn’t there. The particles seemed to be passing through empty space. Only a few of the alpha particles were deflected from their straight path, as Rutherford had predicted.
How are the situations in #6 and #7 different Why do you think this is?
It has minimal change on how the Alpha particles travel. The alpha particles move in the relationship to the nucleus by making very large turns, practically avoiding the nucleus in all costs. I think the situations are different because there’s more protons moving around the foil in #7 than there is #6.
What happened in Rutherford’s gold foil experiment quizlet?
Rutherfords gold foil experiment involved sending positively charged alpha particles through a thin sheet of gold foil and defecting if there was any deflection of the particles. He found that most passed straight through yet some particles showed some deflection.
What did Ernest Rutherford’s gold foil experiment determine?
What was the impact of Ernest Rutherford’s theory? The gold-foil experiment showed that the atom consists of a small, massive, positively charged nucleus with the negatively charged electrons being at a great distance from the centre.
Who did the gold foil experiment quizlet?
Ernest Rutherford- gold foil experiment.
What can a electron microscope see?
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, metals, and crystals.
