7. The charged object can have two polarities, positive or negative which is determined by the configuration of electron orbitals of the material. If there are free orbitals, it will likely gain electrons and produce a negative charge. If there are free electrons on the outermost orbitals, these electrons will be lost and the material will have a positive charge.
8. R<span>ubbing styrene and rabbit fur because rabbit fur has free orbitals which can hold electrons making styrene positive.
9. When it is dry and windy.
10. When there no other materials that can take or add electrons from or to it.
11. Static charge is dissipated through static electricity.
