Static Electricity Flashcards
What are the three subatomic Particles
Electrons, Protons, Neutrons
where are the sub-atomic particles located?
Protons + Neutrons in the nucleus, Electrons in the shells
What is the last shell called in the atomic model
valence shells ( Valence electrons here)
What is conduction
it is the process of transferring charge between objects by touching or rubbing
What is induction
the process of rearranging electrons on a neutral object by bringing a charged object close to it
Example of induction
Rubbing a balloon with fur and bringing it close to water
Example of Conduction
Rubbing a balloon against your hair
How does an object become charged or neutral
It becomes charged or neutral by losing or gaining electrons.
Why cant an object lose protons
An object cannot lose protons because they are in the nucleus
What are the 3 laws of Static Charge
1) Opposite charges attract (+ and -)
2) Like charges repel (- and -) (+ and +)
3) Neutral objects attract charged objects
What’s an Insulator?
A material that doesn’t allow charges to move easily + can build up and keep a static charge
Example of an Insulator?
Glass, Plastic, Ceramics, Dry Wood & Rubber (Balloon)
What’s a conductor?
A material that allows electrons to move freely throughout it + can’t keep a static charge
Example of a conductor?
Metals (Silver, Iron, Aluminum, Copper, etc.)
What is Static Charge?
It’s an electric charge that is collected and held in one place (Doesn’t Move)
