What unit is all matter made up of?
Atoms
Which particle of the atom has a positive charge?
The protons
Which particle of the atom has a negative charge?
The electrons
Which particle of the atom is neutral / hasn't got a charge?
The neutrons
What are the three particles in the atom? (AKA: subatomic particles)
Protons, neutrons, and electrons
What do we call electricity that does not flow?
Static electricity
What type of electricity is this? (Static electricity or electrical current?)
Static electricity
What do we call it when there is an exchange of electrons between many different atoms? (a flow of electrons)
Electrical current
What do we call materials that allow electrons to flow without resistance?
Electrical conductors
What do we call materials that do not allow electrons of move easily?
Electrical insulators
Why are electrical wires made of copper covered in plastic? (Use the words electrical conductor /insulator)
The wire conducts electricity because copper is a conductor but the plastic on the outside of the wire protects us because it's an insulator.
What type of electricity is this? (Static electricity or electrical current?)
Electrical current
