Good Insulators (Easily Gain or Lose Electrons):
* Non-metals:
* Plastic: (e.g., PVC, Teflon, acrylic)
* Rubber: (e.g., natural rubber, silicone rubber)
* Glass: (e.g., window glass, Pyrex)
* Fur: (e.g., rabbit fur, cat fur)
* Wool: (e.g., sheep wool, alpaca wool)
* Silk:
* Amber: (fossilized tree resin)
* Other:
* Paper:
* Dry skin:
Good Conductors (Less Likely to Gain or Lose Electrons):
* Metals: (e.g., copper, aluminum, iron, silver, gold)
How it Works:
When you rub two different materials together, electrons can be transferred from one material to the other. This transfer is due to differences in the materials' electronegativity, a measure of how strongly atoms in the material attract electrons.
* Materials that easily lose electrons become positively charged.
* Materials that easily gain electrons become negatively charged.
Example:
If you rub a glass rod with silk, the glass will lose electrons to the silk. The glass rod will become positively charged, and the silk will become negatively charged.
Note:
* The type of charge generated depends on the materials being rubbed together.
* The amount of charge generated depends on the type of materials, the force of rubbing, and the duration of rubbing.
* Static electricity is the build-up of electric charge on a surface. This charge can be discharged in a sudden spark or shock.
