Determines size of electrical force

Moving of electrons from one surface to another when object's surfaces rub together.

Good conductor

Example of an insulator

Creates a negatively charged atom (ion)

Material that holds tightly to it's electrons, so it doesn't allow electricity to flow

Negatively charged particle found in the cloud surrounding the nucleus

For an atom to be balanced / neutral, it must have the same number of

Rearranging of particles in an object without direct contact.

Like charges

A circuit that allows electricity to flow from the source, through the lode and back to the source is a(n) __

Can act on an object without touching it

A charged plastic block touches a metal ball & transfers electrons to the metal ball. This happens through __.
