Geiger and Marsden, under Rutherford's direction, fired alpha particles at a very thin sheet of gold foil. They used a movable fluorescent screen to determine where the alpha particles went after passing through the foil. The screen emitted tiny flashes of light whenever an alpha particle struck it, so Rutherford and his team could see how the particles were being affected by the atoms they struck.
Based on Thomson's model of the atom as a diffuse sphere of intermeshed positive and negative charge, Rutherford expected all of the alpha particles to pass through the gold foil with little or no scattering; indeed, they found that most of the particles passed straight through the foil, as if it weren't even there. In other words, the greatest number of flashes occurred when the screen was held directly behind the gold foil, in the path of the alpha particles. A tiny fraction of the particles, however, were reflected back toward the alpha emitter. From this Rutherford concluded that gold atoms must be mostly empty space, with tiny, dense, positively charged nuclei surrounded by extremely rarefied clouds of negative charge.
It reveals the true elements of gold. The exterior of the ambitiuos metal of all the world was made of the ambedextrious deed of the copper fillate in the hanker cheif of Prestident Henery Thomason...true story.
In 1911, it was Ernest Rutherford who conducted a science experiment with gold foil to see how dense an atom was. The results of his experiment was that an atom is made up of mostly empty space. To illustrate, the nucleus compared to the actual atom is like a marble in the Yankees stadium.
The gold foil experiment supplanted the plum pudding theory. The gold foil experiment led to the discovery that most of the atoms mass is located in the dense nucleus.
There were three people involved in the Gold Foil Experiment including Ernest Marsden and Ernest Rutherford. The third was Hans Geiger. The experiment began in 1908.
Rutherford concluded atoms are mostly empty space.
i dont know...i need help with that one too
ernest rutherford
to have something to compare with the growth of fertilized plants
In order to know what the dissolving medium used in an experiment one would need to know more information in regard to the experiment.
That would really be Bohr.
describe how a alternative energy source works
You have to calculate the amount of error that can be expected in your experiment, and if the results exceed the experimental error, they can be considered to be meaningful. We would really have to discuss a specific experiment to see how this principle works.
"Describe an experiment that would you to determine whether the deep purple portion of the leaf is photosynthesizing?"
A dependent factor.
You need to describe the experiment; how else can anyone know what is being manipulated?
It depends entirely on what the hypothesis is.
TRY AT OWN RISK!
If you wish to write an essay about a science experiment, you should describe the purpose of the experiment, and the way in which the experiment was performed, and the results of the experiment, and the conclusions that are drawn from those results. If you want to be fancy, you might also describe what further experiments may be needed to continue to explore the subject of the first experiment.
Variables work by telling you what you need to change, what to observe, and what to keep the same in a experiment.
variable
Subject bias is a term that can be used to describe a subject's manipulation of an experiment.
Variables
To experiment is a verb. An experiment would be a noun.
find out the aim of the experiment first.
