1.
1 point
The law of electric charges states that unlike charges (attract/repel) each other.
2.
1 point
Static electricity is the build-up of electrical charges on an object.
3.
1 point
When atoms gain extra electrons, a (positive/negative) charge is created.
4.
1 point
Atoms have two types of charges, (_____ and _____).
5.
1 point
One type of electricity is called:
6.
1 point
A _____ is a device that can open and close a circuit.
7.
1 point
Protons are found in the _____ (center) of atoms.
8.
1 point
An _____ has a negative charge of -1.
9.
1 point
All matter is made up of _____.
10.
1 point
In the (on/off) position, the switch closes the circuit and completes the route for flowing current.
11.
1 point
If an atom loses electrons (negative charges), this would create a (positive/negative) charge, because it would have more protons than electrons.
12.
1 point
Who (_____ _____) invented the generator which helped to make electricity available to all people.
13.
1 point
Some atoms tend to lose _____.
14.
1 point
_______ electricity is the flow of electricity through a conductor.
15.
1 point
Usually, atoms have (the same/different) number of electrons and protons.
16.
1 point
If the charges of two objects are (the same/opposite), they will attract each other.
17.
1 point
As the number of "free" electrons (increases/decreases) in the material, it becomes more capable of creating an electric current.
18.
1 point
Another type of electricity is called:
19.
1 point
The law of electric charges states that like charges (attract/repel) each other.
20.
1 point
If you rub things together, electrons can move from one atom to another.
21.
1 point
The movement of "_____" electrons produce the flow of electric charges.
22.
1 point
_____ spin around the nucleus.
23.
1 point
If the atom has no charge it is:
24.
1 point
A _____ has a positive charge of +1.
25.
1 point
In the (on/off) position, the switch places a gap in the path, which prevents any current from flowing.
26.
1 point
Electricity is the flow of (positively/negatively) charged particles (electrons) from one area to another.
27.
1 point
If the charges of two objects are (the same/opposite), they will repel each other.
28.
1 point
The electrons in the (innermost/outermost) part of the atom are held more loosely, and sometimes these electrons are lost.
29.
1 point
Electricity occurs when (negatively/positively) charged particles (electrons) flow from one place to another.
30.
1 point
Atoms can lose electrons when objects are rubbed together.
31.
1 point
A circuit must be (open/closed) in order for electricity to flow.
32.
1 point
_______ electricity is the build-up of electric charges on an object.
