the dust particles keep the electrons inside and remake them they dust particles can be swept off but a few remain inside the insulator!!!
this is very confusing!!! :)
Static electricity can't move in an insulator and it will only lose it's charge if it is earthed.

Why does a rubbed plastic object stay charged but a rubbed metal object lose its charge?
Plastic is an insulator where as metal is a good conductor
Do insulators conduct charge?
Yes. The idea of an insulator, however, is that it doesn't conduct much electricity. Some electricity (electric charge) will always be conducted, but not much if the material is called an "insulator".
What will happen if you nearly touch charged insulator?
An insulator does not generally hold a charge, in fact they resist the flow of electrons, this is what makes them insulators. In some cases though, you can build an electrical charge by rubbing a material (usually fibrous like carpet, wool or hair) with an insulator, though not all insulating materials under all conditions. Mostly this works in cold dry conditions because the air itself will act as an insulator not allowing the static electricity to dissipate through the atmosphere. This is why you get shocked in the winter more than in the summer when you grab a doorknob. As for the charge now accumulated on the insulator, think rubber balloon rubbed on hair, It will tend to stay there until it finds a path to ground. Then the charge will dissipated from the area surrounding the contact, but the areas further away may not dissipated because the electrons can not move across the insulator. To sum it up, the electrical charge will transfer to the conductor but an insulator will not charge under normal circumstances.
How can you create a static charge on an insulator?
If they are made of different materials and are both insulators.
Why is aluminum foil a bad insulator?
The reason that some materials are good conductors (of electricity) is because the outer electrons of the atomic nucleus are easily pulled away by an electric charge and if you keep applying that charge (such as with a battery) a current will flow. A good conductor is just the same as a bad insulator.
Why does a rubbed plastic object stay charged but a rubbed metal object lose its charge?
Plastic is an insulator where as metal is a good conductor
In order to build up a charge does a material need to be a conductor or an insulator?
no....absolutely not...to acquire charge, either the material(atoms to be specific) must lose some electrons or gain some....eg. rubbing a glass rod and wool
What is a material that does not conduct electrical charge?
Rubber is one. :)
Do insulators conduct charge?
Yes. The idea of an insulator, however, is that it doesn't conduct much electricity. Some electricity (electric charge) will always be conducted, but not much if the material is called an "insulator".
How can an electrical conductor lose its effect?
In order for it to lose its effect you have to put an insulator around it, such as rubber or plastic.
Can charge flow easily through insulators?
"Insulator" means that electrical charge can NOT flow through it easily.
What is the only methold to charge an insulator by?
An electrical charge could be added to an insulator from another source of charge such as a voltage supply, or maybe from a Van de Graaff belt generator. {The one I used generated 50MV at about 12x10^-6 Amperes. }
What is a substance that does not allow electricity to pass through it easily?
Insulators - they cannot allow electricity to flow through them as they have no mobile charge carriers present. Insulators - they cannot allow electricity to flow through them as they have no mobile charge carriers present.
Is the picture tube a conductor or an insulator Explain your answer?
A picture tube is an insulator. The electrons would gather up and so, create an electric charge when the TV is on. If it was a conductor, the charge would not build up. Hope this helps :)

How are conductors and insulators different give an example of a conductor and an insulator?
conductors, such as metals, have free electrons, meaning their electrons are not strongly bonded to the atoms and a charge can move easily throughout the whole object, an insulator such as wood does not have free electrons so a charge is likely to stick in one area of the insulator.
Is sodium chloride is a good insulator of electric current?
Yes Sodium Chlorine is a good insulator because there is not lose electrons to participate in the current flow
