Yes.
An alpha particle is the nucleus of a helium atom, with no electrons. There are 2 protons and 2 neutrons.
An alpha particle is the nucleus of a Helium-4 atom; therefore, it has 2 neutrons and 2 protons. A gold atom has... well, much more protons and neutrons, you can look it up if you like. Also, a gold atom normally does have electrons, whereas an alpha particle is just the nucleus (i.e., no electrons). You decide for yourself how "similar" those two are.
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.
No. 92235U is a radioisotope with 92 protons, 143 neutrons, and (in a non-ionic, neutral state) 92 electrons. An alpha particle, on the other hand, is a helium nucleus, 24He2+ with 2 protons, 2 neutrons, and no electrons. It happens that 92235U decays by alpha decay to 90231Th with a half-life of 7.04 x 109 years, but this does not means that it is an alpha particle, it means that it emits an alpha particle. It also decays by spontaneous fission with a probability of 7 x 10-9%. It primary value, however, is that it is fissile, meaning that if it absorbs a thermal neutron, it will undergo fission, generating more neutrons, two new isotopes, and energy.
Yes. If it has fewer electrons that protons, it will be a positively charged ion, and if it has more electrons than protons, it will be a negatively charged ion.
When a particle loses electrons, it becomes positively charged due to having more protons than electrons. Conversely, if a particle gains electrons, it becomes negatively charged as it has more electrons than protons. This imbalance in charge leads to the formation of a charged particle.
An alpha particle is a helium-4 nucleus. It has two protons and two neutrons, and we write it like this: 24He++ or more commonly 24He2+ Some links can be found below.

An alpha particle is two protons and two neutrons (same as a Helium nucleus) so when a nucleus ejects an alpha it will defintely have less mass. Also it will be a new element because it has two less protons.
Its charge would be negative, since there would be more electrons than protons. However, there is no chemical process that can cause a sudden loss of a bunch of protons from the nucleus of an atom. Alpha decay can cause an atomic nucleus to expel an alpha particle, which consists of 2 protons and 2 neutrons, and there is such a thing as proton decay, but that is extremely uncommon.
When an atom has more protons than electrons it is called an ion. This is a positively charged particle because it has more protons than electrons, thus the positive charge takes over.

An alpha particle. It is also a helium nucleus and has a charge of +2e. The ejection of an alpha particle occurs whenever the electromagnetic force overcomes the strong force in a nucleus and needs to rid itself of excess charge. The reason that a single proton is not simply ejected has to do with the stability of the alpha particle itself which is generated by the strong force. If there were more protons in an alpha particle, it would not hold together properly. It cannot have more neutrons because it simply wouldn't be ejected because of strong force.
The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
