What is the number of electrons?
300
When an atom gains or loses an electron.
What is an ion?
300
This is an ionized substance that becomes highly electrically conductive to the point that long range EM fields dominate its behavior.
What is plasma?
300
The variable that is manipulated in an experiment.
What is the dependent variable?
400
