Staric Electricity Quiz Flashcards
Identify the subatomic particles in an atom. Name them, listed charges and where the particle is located.
Proton- in the nucleus+
Electron- on the energy shells -
Neutron- neutral=
Which subatomic particles move in order to create static electricity.
Protons and electrons
What charges created when an object loses electrons
Positive charge
What charges created when an object gains electrons
Negative charge
what does it mean if a substance is electrically neutral
It has both equal amounts of protons and electrons.
State the laws of electric charge
-objects that have opposite charges attract each other: negative attracts positive and positive attracts negative.
-objects that have the same charges repel each other negative repeals negative and positive repels positive.
-neutral objects attract charged objects neutral attracts positive and neutral attracts negative.
What is the difference between an insulator a conductor and a semi-conductor. List two examples of each.
Insulators- a material in which electrons cannot move easily from one atom to another. Non-metals (Wood, rubber, plastic)
Conductors- a material in which electrons can move easily between atoms. Metals (Copper, silver, aluminum)
Semiconductors- a material in which electrons can move fairly well between atoms. Non-metals (silicon)
Define grounding. Describe the process of neutralizing a negatively charged object in a positively charged object.
Grounding- an object that can neutralize a charged object.
Supplies a large number of electrons to the charged object or removes a large number of electrons from the object.
What are the three different ways static electricity can be created?
Charging by friction
Charging by conduction (contact)
Charging by induction (a charged object held near a neutral object)
What is the electrostatic series
a list that places materials in order according to their tendency to receive or give up negative electrical charges
