Why in 1911 Rutherford and his co workers were surprised when they shot a narrow beam of alpha particles through a thin sheet of gold foil?

his theory was that the alpha particles would pass straight through the gold atoms with slight deflection due to the positive charge thought to be spread out in the gold atoms.
When they tested the theory, they were suprised that a great majority of the alpha particles passed staight through the gold atoms withought deflection. even more suprizing a small fraction of the alpha particles bounced off the gold foil at very large angles. some even bounced strait back toward the sourse. Rutherford later recollected"this is almost as increadible as if you fired a 15 inch shell at a peice of tissue paper and it came right back and hit you"

Do dosimeter badges detect any exposure to alpha particles when worn by radiation workers?
No, alpha particles will not be detected by dosimeter badges.
What precautions do workers in a nuclear power plant have to take?
Radiation suits are completely fake. Radioactive materials need to be encased in shielding to make sure people are protected from them while being handled. There are often Graded-Z barriers, which are made up of several different compounds that block different radioactive particles generated by a reactor. In addition, workers wear radiation/particle detectors that monitor their radiation exposure.
What are the reasons why radiation workers are given higher dose exposure limit is it good or bad?
suggest reasons why radiation workers are given higher dose exposure limits
What is the difference between incentive and impetus?
Incentive....the workers were given added incentive to finish the job by being given a bonus if they worked over the weekend.impetus...the firestorms in southern California were given added impetus by the strong winds that were blowing through the area at the time.
Why do manual workers need more energy than office workers?
Manual workers needs more energy than office workers because they use more energy by doing more physical movement
What did the particles in Rutherford' s experiment do?
Rutherford was expecting the result to be what JJ Thomson had predicted. That the Alpha Particles just pass through the gold foil, not rebound, like the result. JJ Thomson thought of this result because of his plum pudding model.
If Rutherford made bombarded aluminum foil with alpha particles instead of gold foil what observations would he have used?
The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum. If the foil were too thick, there would be no transmission of particles at all; the whole point was to demonstrate that most alpha particles passed through unchanged, but some of them scattered, which is only possible with a VERY thin foil.
What has the author Blair A Rutherford written?
Blair A. Rutherford has written: 'Working on the margins' -- subject(s): Postcolonialism, Race relations, Tobacco farmers, Tobacco workers
Is affiliated workers association a scam?
You'd be surprised how little they cover. Most hospitals don't even recognize them.
Do dosimeter badges detect any exposure to alpha particles when worn by radiation workers?
No, alpha particles will not be detected by dosimeter badges.
Can unused wind blown Gunite particles be dangerous to an indivuals health.?
Gunite particles can be dangerous to health. For workers routinely exposed to the particles, OSHA says that silicosis can develop.
What was Rutherford B. Hayes role in the great railroad strike of 1877?
Rutherford B. Hayes was the president during this time. His role was to try and resolve the issue while pleasing not only the railroad workers but also the rest of the country.
What mills pose the greatest danger to their workers from exposure to airborne particles?
Only workers in mills that manufacture yarn, thread, or fabric have a significant risk of dying of this disease.
What flaws exist in Thomson's plum pudding model of the atom?
The plum pudding model of the atom was not correct. The prediction that alpha particles would pass through a sample of matter and would be deflected only minimally was disproved by rutherford and co-workers who found that some alpha particles (1 in 8000) bounced almost straight back. This was explained by the presence of a nucleus. Other phenomena were also difficult to explain. For example atomic absorption spectra with the sharp, principal and diffuse lines.
What is Workers' College's motto?
Workers' College's motto is 'Education through Civil Service'.
How many workers are exposed to the risk of byssinosis?
More than 800,000 workers in the cotton, flax, and rope-making industries are exposed in the workplace to airborne particles that can cause byssinosis.
What term refers to a workers organization that advocates the needs of the workers through collective bargaining?
The labor union
