Noble gases do have outer energy levels that are completely filled. However, it is not true that these gasses form bonds easily. In fact, because all of the potential "spots" for electrons are already filled, the noble gas is very stable and has no need to bond with other atoms. Because of this, noble gases very rarely chemically bond.
That is true if the outer energy level is COMPLETELY filled. If it is almost filled but has one missing as in the case of the halogens, then the atom would be very reactive.
False.
Electrons are bound to the nucleus by the electromagnetic force which is about 100 times weaker than the strong force.

distance from the atomic nuclei
Between protons and electrons.
Plasma
Plasma is a gas where the "temperature" is so high that all the electrons have been removed from the atoms, leaving just the positively charged nuclei and free electrons. There can be no molecules in a plasma as without electrons the bare atomic nuclei repel each other.
Alpha particles are repelled by atomic nuclei because alpha particles have a positive charge, and so do atomic nuclei. The positive charge on the surface of a nucleus will repel another positive charge, like an alpha particle, because of the law of electrostatics. That's the simple answer. And it is correct. But know this: Alpha particles were used in the early investigations of atomic structure and atomic interactions. The alpha particles were used to bombard atomic nuclei, and there are times when an alpha particle will be absorbed by an atomic nucleus. Somehow the laws of electrostatics took the day off, and the fact that absorption took place opens the door to discovery and discussion of other atomic forces. Word up.
False. Electromagnetic force.
distance from the atomic nuclei
In the electrostatic forces between the positive atomic nuclei and the negative atomic electrons.
Atomic nuclei (and alpha particales, but these are exactly the same as Helium nuclei)
Between protons and electrons.
Electrons are naturally to be found in shells surrounding atomic nuclei.
Delocalized valence electrons moving between nuclei become detached from their parent atom. The metal is held together by the strong forces of attraction between the delocalized electrons and positive nuclei.
Plasma
In a covalent compound some electrons are shared between at least two atomic nuclei.
The protons and electrons fuse to form neutrons.

With a covalent bond, atomic nuclei are sharing some of their valance electrons, which means that the electrons are in orbit around both (or all of) the nuclei in question. With an ionic bond, valance electrons are transferred from one atom to another. Once transferred, the electrons orbit only around the atomic nucleus that has received them.
