When atoms of beryllium are bombarded with alpha particles an atom of carbon is produced and a neutron is emitted What kind of nuclear reaction occurred?
Nuclear Fission. The Nucleus of the Atom has been split apart.
What is an appropriate model that has been developed to describe atomic structure?
The best model to describe atomic structure is the Rutherford model
Why do atoms become elements?
Atoms do not 'become' elements. If it exists as an atom it has always been some type of element from the moment it came into existence. An atom is the smallest piece of an element that is still that element. If you break it down any further you neither have any element or atom, you have subatomic particles.
How many crystals have been identified?
4000
Which particle's are found in the nucleus of an atom?
It depends in where you want to end your search. The "larger" particles are protons and neutrons.These in turn are made up of quarks - Protons are made of two Up and one Down quark. The neutron is made of two Down and one Up quark. The difference is that Up quarks have a 2/3 positive charge and the Down has a 1/3 negative charge.At the present time no proposal has been made for quark building blocks,
What structure of the atom has been described as having a dense center that contains subatomic particles?
The Nucleus.
What is the instrument that first took a picture of an atom?
So far, no picture of an atom has ever been taken. Atoms are fundamental particles which have only been visualized and not seen.
Why is indirect evidence important in studying the structure of the atom?
The atom is far too small to ever be examined directly. The diameter of a typical nucleus is only about 1/100,000 of the diameter of the entire atom and if an atom were magnified until it was as large as a football stadium, the nucleus would be about the size of a grape. Nearly all evidence of an atom's structure has been theorized.

If the Thomson model of the atom had been correct Rutherford would have observed?
Before we state the results of the Rutherford gold foil experiment based on the correctness of the Thomson plum pudding model, let's back up and review just a bit. Atoms were thought to be made up of electrons distributed in a positive "matrix" of sorts. With the electrons "evenly distributed" throughout the volume of the atom, a parallel or comparison was made to plum pudding. The plums, which were "scattered" throughout the pudding, were thought of as the electrons in the atom. This is the basis for the plum pudding model of the atom. The gold foil experiment that Rutherford proposed was set up, and alpha particles were "fired" at gold foil from an alpha source (alpha emitter). As the alpha particles were known to be massive compared to an electron, an experiment on atoms conforming to the plum pudding model of the atom would show that the alpha particles zip right through. There would be nothing anywhere near as massive as an alpha particle in the plum pudding atom to stop or scatter them. All the alpha particles would strike the target screen behind the foil in a direct line from the source. When the experiment was actually conducted, most of the alpha particles struck as expected. But a few were scattered in different directions, and this was "impossible" if the atom was constructed as suggested by the plum pudding model. What internal structure in the plum pudding atom could possibly deflect (scatter) a few (or any!) alpha particles? The plum pudding model was set aside, and Rutherford's suggestion was that most of the mass of the atom was concentrated as a positive charge in the center in what we call a nucleus.
Which particle has the least mass and where is this particle located in the atom?
The smallest particles that have been discovered and that don't only exist in theory are the quarks. They are what make up protons, neutrons, all kinds of baryons, and a few other categories of particles. But there is a theory of smaller particles that make up quarks, electrons, and other particles that were previously believed to be fundamental (But, again, these particles only exist in theory). These particles are to be called "rishons" if discovered.
How many alpha particles are produced as one atom of uranium-238 decays to an atom of lead-206?
4 alpha particles were emitted. This is known by the fact that an alpha particle ,on being given out, decrease the mass number of the element by 4.Hence the decrease in mass number in above question is 12 which itself states the answer that 4 alpha particles are emitted. The number of beta particles emitted are 3 beta particle have been emitted.
