Atoms
What is the charge of a Proton
Positive
How can you tell how many protons an atom has
By the atomic number
What is static electricity
A charge by rubbing two things together
What is a circuit?
A closed path through which a continuous charge can flow.
What is an atom
The smallest material that makes up everything else
What is the charge of an Electron
Negative
In a neutral atom the electron count is the same as the?
Protons or atomic number
Where does electricity come from.
The movement of electrons
What is an open circuit
A circuit that does not have a continuous flow of current.
What is an electric charge
Property that allows an object to exert an electric force on another object without touching it
What is the charge of a Neuteron
Neutral
Where is the atomic mass found on the periodic table
The number on the bottom
What is charge by induction
Charged by non contact
What is one advantage and disadvantage of a series circuit
Easy to build, use less material, one thing goes out they all go out
What is a molecule
Two or more atoms bonded together
What is the net charge of the atom
3 electrons
2 neutrons
4 protons
positive 1
How can you find the number of neutrons
take the atomic number away from the atomic mass
What is an electric field
the space around a particle where an electric charge can exert a force
Whay is one advantage and disadvantage of a parallel circuit
If one thing goes out the rest will work, they take more material and are harder to build
What is magnetism
force of attraction or repulsion between two objects
What is an ion
An atom with a charge
How many neutrons does Sn have?
69
What is resistance?
property of a material that determines how easily a charge can move through it
What do you measure resistance in?
Ohms
Why can't you trust atoms?
Because they make up everything.
