_______ are very small particles that make up allmatter in the universe.
 Elements
 Cells
 Atoms
 Charges
atom
Label  the parts of an atom:
Electron
 Neutron
 Proton
periodic table
 Nucleus
 Protons
They are negatively charged particles:
 Electrons
 Neutrons
molecule structure vector
They are positively charged particles:
 Protons
 Electrons
 Neutrons
 Nucleus
think
This particles are neutral, they do not have a charge:
 Nucleus
 Protons
 Electrons
 Neutrons
electricity
The positive and negative charges are the reason
why electricity exists.
 True
 False
think
 Normally, an atom will have less protons than electrons,
so the atom has a negative charge.
 Normally, an atom will have the same number of protonsand electrons, so altogether, the atom has a charge ofzero, it is neutral.
 Normally, an atom will have more protons than electrons,so the atom has a positive charge.
What is true about atoms?
electricity
_________ can move easily and pass from one atom
to another.
 Protons
 Electrons
 Neutrons
electricity
When an atom does not have the same number of protons and neutrons, the atom has what we call...
 an electric charge
 a generator
 a nucleus
 an electric circuit
idea
If an object has more protons than electrons, it has a...
 negative charge
 neutral charge
 positive charge

It is the flow of electric current through a conductor.

When two objects come into contact with each other
(for example, your hair and a balloon, pen with paper...),
electrons pass from one object to another.Later they jump back to the positively charged object.We call this...

thinking
They are materials that transmit electric current easily.

 Resistors
electricity
They are materials which only let a specific amountof electric current pass.

True or false?
When the switch is in the position ON the circuit is closed
and the electricity can pass.
