Electrons are ripped off one material and held tightly by the other material.
the electrons get ripped off one object and held by the other The rubbing moves electrons to the object that holds them more tightly.
When two materials rub together, the loosely held electrons of one material move to the material with the more tightly held electrons.
tightly bound in place.
No. The best conductors are metals (esp copper), which have loosely bound electrons.
Because they have free electrons. The electrons are not tightly bound to the nuclei of their atoms and are free to drift around the metal, carrying electric charge through it.

Materials carry current because of the way the electrons of the material behave. Current is proportional to the number of electrons. If the electrons are loosely bound on the material then they are available to carry current along the material. Copper is a common metal who's configuration means that the electrons are loosely bound and as such is very good at carrying current. If on the other hand the electrons are tightly packed into the atoms in the material then they aren't available to carry current. Materials such as glass and plastic are good examples.

yes
Electrons found in the K shell are more tightly bound compared to all other shells. This is because it is the innermost shell and is closest to the nucleus.
Mercury easily shares its valence electrons
Electrons are never connecting with the nuclease of an atom, the electrons do pass more freely if that's what you mean though.

Valence electrons are the electrons least tightly held by the atom and by definition are the electrons in the outermost shell of the electron and are highest in energy. They are the electrons that often contribute to an elements reactivity and in the case of Sodium, which as one valence electron in its ground state, it "gives up" its electron when it comes in contact with water.
If it is tightly sealed and not exposed to direct sunlight its shelf life should be indefinite.
