How does Rutherford's model of atoms explain the deflection of alpha particles by gold foils?
Rutherford's model of the atom suggested that atoms have a small, dense, positively charged nucleus at the center. When alpha particles (positively charged) were shot at gold foil, some were deflected at large angles or even reflected back. This indicated that the positive charge and mass of the nucleus were significant enough to affect the trajectory of the alpha particles.
What were The targets used in the alpha particle atomic experiments in the early 1900's?
Gold foil was typically used as the target in alpha particle atomic experiments in the early 1900s. This was famously utilized by Ernest Rutherford in his gold foil experiment to study the structure of the atom.
Why in gold leaf electroscope sides parallel to the gold leaf are tin foils?
The tin foils on the sides of a gold-leaf electroscope help to discharge any excess charge quickly, allowing the gold leaf to return to its neutral position. The tin foils also help shield the gold leaf from any external electric fields that could interfere with the electroscope's measurements.
What energy is released from nuclear disintegration?
I am assuming by what you mean what type and by nuclear disintegration you mean decay not fission.It depends on the type of reaction. Gamma rays (defined as x-rays coming from nuclear events), alpha particles (fast helium nuclei), beta rays (fast electrons), positrons (anti-matter electrons! that usually combine with an electron and release gamma rays) and even neutrinos (fast light weird particles that wouldn't be stopped by a light year's thickness of lead) are all possible.As for the useful release of energy in the form of some sort of power for a battery or device, there are basically three sorts, listed in approximately in order of usefulness:Radioisotope thermal generators. Usually use alpha particles emitting isotopes like Plutonium-238 and Polonium-210, because alpha particles are energetic but easy to stop (a single thickness of aluminium foil is more than sufficient). The energy comes in the form of heat which is generated when the alpha particles crash into something and are absorbed. The heat is either used directly, say to keep a spaceship's computer warm enough in the cold void of space to function properly, or can be converted to electricity with a heat engine (eg. steam engine) or a Peltier device (an electronic device that produces a flow of electricity by having heat flow through it, or conversely can cause a heat flow if powered electrically, turning it into a combined heater and refrigerator).Radio luminescence. These use phosphors like in a fluorescent light bulb mixed with a radiation source. Bombardment with radiation causes the phosphor to glow. Either an alpha emitter such as Radium is used, or more recently a beta emitter like Tritium (Hydrogen-3), used in America for emergency signs, trilux glow in the dark gun sight inserts, and even novelty key rings!Gamma sources aren't practical because the gamma rays are too penetrating. Which means as well as exposing users of the device to dangerous radiation, only small fraction of the radiation is useful as the rest escapes.As well as directly using the light there have been devices such as watches that use a combination of a radio luminescent source and a photocell (what a solar cell is called when it isn't being shined on by the sun) to provide electrical power.Direct electrical conversion. Charged radiation such as beta rays are collected directly to provide a charge source in a similar way to a chemical battery, and/or by their great velocity act on electric or magnetic fields to produce useful electricity, similar to a generator. Another example of direct electrical conversion uses spaced metal foils bombarded by gamma rays. The gamma rays knock electrons off one metal foil where it is collected by another. Then electric current can flow when the plates are connected in a circuit. How one foil is affected and the other not I don't know. Perhaps one is in the line of fire of the gamma rays and the other isn't?As well radioisotopes are used in applications like using the gamma emitters Cobalt-60 for doing x-rays or radiation therapy without requiring electricity. For this use it is usually kept in a lead can with a thin hole drilled in the top. Usually it is covered with a lead shutter, but that is swung aside when the x-ray is to be taken, exposing the x-ray film and the target object in between to the Cobalt-60 source and the gamma rays it produces.
What balance the electric force of repulsion make the leaves don't separate further?
The simple metal foil electroscope has its leaves propelled apart by electrostatic forces repelling each other. Traditionally gold foil was used as the metal, (for it may be made very thin) but I imagine that today metallized plastic foils are lighter and will achieve greater separation. But you have to consider the net direction in which the charged foils will exert maximum force against each other.
In Rutherford experiment why wouldn't the electrons in the atoms of the gold foils affect the paths of the alpha particles?
Electrons are so small that they have no affect. The alpha particles were 2 protons and 2 neutrons being shot thru, even though the electrons have a negative charge..they are so small and take up so little space, the alpha particles probably n ever even came near them.

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.
Briefly describe Rutherford's experiment?
The Gold Foil Expirament-Rutherford A line of photons were shot through a thin piece of gold, and rutharford theorized that they should pass through. However some passed through while others deflected and some reflected backwards. It gave proof that atoms have a nucleus

When was Luke Foils the Villain created?
Luke Foils the Villain was created on 1916-02-14.
When did Magic: The Gathering start producing foils?
Magic: The Gathering started producing foils in 1997.
Can beta rays pass through 1cm thick aluminium foil?
No, it cannot. Alpha particles can be stopped using aluminum foil. Beta particles (electrons) posses higher kinetic energy and have smaller cross section. Lead is widely used to stop beta particles as well as gamma particles. Gamma particles are basically high energy photons which are extremely dangerous for alive creatures. Extra precaution must be taken when you are working with such radiation.

Who explained the behavior of positively charged particles being deflected from a metal foils as the nucleus?
Ernest Rutherford explained the behavior of positively charged particles being deflected from metal foils as they interacted with the nucleus of the atom in his famous gold foil experiment. This experiment led to the discovery of the atomic nucleus as a small, dense, positively charged center within the atom.

How much does highlights cost?
It all depends on how many foils you get. 7 foils are about 20-30 also depending on the stylist.
