Alpha particles are far more massive. Alpha particle is an (ionized) helium atom, a beta particle is just an electron.
Several feet.
They have low velocity
The ramp method best explains the particle model as far as buoyancy is concerned.
This depends on their energy. An alpha particle that comes from nuclear decay is usually only able to travel a short distance, a few centimeters, through air. Alpha particles as cosmic rays, however, are much more energetic, and can penetrate quite deeply, even through many meters of solid shielding. These can penetrate the atmosphere.

Gamma, as it has the most energy by far.

An electron is the basic carrier of the negative electrostatic charge. It has an anti-matter equivalent (an anti-particle) called the positron. Either an electron or positron can be a beta particle. The reason is that beta decay releases a beta particle, and the type of particle will depend on the type of decay. In beta minus decay, the change in an atomic nucleus will release an electron, and in beta plus decay, the nuclear change will release a positron. Use the link below to learn more about beta decay.
That depends on the energy of the beta particles and the medium they are passing through. In air beta can travel several inches to several feet. Beta cannot pass through a single layer of aluminum foil.
The highest energy state is gas.
Because, as far as I know, people can not move air with their minds.
The ability of particulate radiation to penetrate human tissue varies by particle type, and to some degree on the energy of the particle. The three basic types of particulate radiation are the alpha particle, the beta particle and the neutron. Let's look at them. The alpha particle won't penetrate very far at all. As the alpha particle is a helium-4 nucleus, it is massive, and it will be stopped by the outer most layers of the skin. As for beta particles, which are electrons or positrons, they can't go much farther. They'll be stopped before much penetration into the skin. That leaves just one other particle: the neutron. Neutrons have an extreme ability to penetrate tissue. They can do some serious damage, and we don't want to be on the receiving end of them. There are some other particle types, but they aren't generally seen outside the physics lab. These are the "big three" types of particulate radiation, you'll find links below to help you discover more.
You can't. There is no level limit in bf3 beta as far as i know.
So far, the "quark" is believed to be the most tiny fundamental particle.
Yes, we are up to iOS 7 beta 4 so far and this beta is available to iOS developers.
