19-20 Flashcards
positive charge
when an atom has more protons then electrons
negative charge
when an atom has more electrons then protons
neutral charge
when an atom has equal amounts of protons and electrons
columb
the SI unit of electric charge,
charge quantization
the principle that the charge of any object is an integer multiple of the elementary charge.
ion
atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
insulator
a material that is not good at conducting electricty
conductor
a material that is really good at conducting electricty
semi conductor
a material that is somtimes good at conducting electricty
electrons
negativly charged particles in an atom- carries electricty
neutrons
a particle with a nutural or no charge found in atoms
protons
a postivly charged particle found in an atom
tribo electric charging
when two objects rub to gether and become charged
columbs law
like charges repel and opposite charges attract
electric field
a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
