Yes!!
That is why they do not allow any form of energy to penetrate into the insulator.
Electrical conductor
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.
Atoms are bonded in ionic crystals.
Metallic bonds form when the valence electrons of a metal become dissociated from individual atoms and join a mutually shared electron pool. This phenomenon can only happen if these electrons are loosely bound to their atoms, which is a characteristic of metals. Nonmetals and metalloids hold on to their valence electrons too tightly for this to occur.
Electrical conductor
In electrical insulators electrons are not able to move freely.
insulator
Conductors allow most, if not all, electricity to pass through it. This is due to "wandering electrons" that aren't tightly bound to the nucleus of the conductor itself.Resistors conduct some, but not all electricity to pass. It somewhat resists it, hence resistors.Insulators do not allow electricity to pass through it due to the electrons being so tightly bound to the nucleus.
Conductors, most metals for example, valence electrons of the atoms can be localized with very little input of energy. Insulators, most non-metals for example on the other hand, offers high resistance to flow electrons through them. In insulators valence electrons of the atoms are tightly bound and therefore at low voltages there is no flow of electrons through them.
The valence electrons in the otermost shell of an atom are from an energy point of view the easiest to rmove or share with other atoms. The inner sheel alectrons are much more tightly bound. The important measure of this energy is the ionization energy.
tightly bound in place.

No. The best conductors are metals (esp copper), which have loosely bound electrons.
Atoms are bonded in ionic crystals.
The outer shell is the valence electrons and they are very loosely bound to the nucleus - less force by the nucleus on the valence electrons, so valence shell's electrons are exchanged first in any reaction.
