The world is made of tiny particles that cannot be seen with the naked eye. These particles are called atoms. Atoms make up all matter and are made up of three types of particles that cause electric charges. Click the buttons below to learn more.
Many atoms have no overall electric charge because the protons and the electrons of an atom are equal. However, atoms can become unbalanced. Atoms rarely lose their protons, but electrons often move between atoms. If an atom gains more electrons than protons or more protons than electrons, the atom is unbalanced and develops an overall electric charge.
When an atom has more protons than electrons, it has an overall positive charge.
When an atom has more electrons than protons, it has an overall negative charge.

What would increase the chances of an electric charge forming?
An action can help cause electrical charges to form. For example, rubbing an object on another object could increase the chances of electrical charges forming. This happens because rubbing increases the movement of electrons between atoms and causes them to become unbalanced and have an overall charge.
Check for Understanding:
1. Atoms make up all matter and have three particles that can cause electric charge.
2. Protons have a positive charge, electrons have a negative charge, and neutrons have no overall electric charge.
When atoms have a negative or positive overall charge, they create electric force. Electric force is a push or pull between matter with different charges.

Check for Understanding:
1. Electric force is a push or pull between matter with different charges.
2. Objects with the same overall charge will repel.
3. Objects with opposite overall charges will attract.

Static electricity is a buildup of charged subatomic particles on an object. Click on the numbered buttons to explore how static electricity works.
Question 10
10.
Static electricity is a__________of__________subatomic particles on an object.
Question 11
11.
Conservation of charge states that electrons cannot be destroyed when an object becomes charged. Objects can only take or give electrons to other objects. Two objects can become charged when objects are rubbed together from friction. Electrons move from one object to another. The object that loses electrons becomes positively charged, and the object that gains electrons becomes negatively charged.
One object can become charged when a charged object directly touches it through conduction. Electrons transfer from the object with a more negative charge to the object with a more positive charge.
Charges can also be rearranged within an object through induction. This ruler has a negative charge. When it is moved near the metal knob, electrons in the metal knob are repelled and move to the end of the knob. The front of the knob then has a positive charge, and the end of the knob has a negative charge.

The slippers become charged after rubbing on carpet through__________
Check for Understanding:
1. Static electricity is a buildup of charged subatomic particles on an object.
2. There are three ways objects can become charged.
• Electrons can move from one object to another as two objects rub together through friction.
• One object becomes charged when it directly touches a charged object through conduction.
• Electrons of an object can rearrange themselves when placed near a charged object through induction.
1. Atoms make up all matter and contain neutrons, electrons, and protons.
2. Atoms can gain an overall electric charge when particles move from one atom to another and cause them to become unbalanced.
3. Electric force is a push or pull between matter with electric charge.
•Like-charged particles repel each other.
•Oppositely charged particles attract each other.
Question 14
14.
Drag up the labels to correctly identify the overall charge of each object.
Other Answer Choices:
neutrons
electrons
positive
Question 15
15.
A proton has a__________charge, and an electron has a__________
charge.
Question 16
16.
There are an equal number of protons and neutrons in the atom. Therefore, the particles in the atom are balanced. Balanced atoms are neutral, or have no overall electric charge.

Which object below would attract a negatively charged object?
Gina is running across the floor. As her sock rubs against the carpet, what most likely happens?
Electrons will move between her sock and the carpet.
Neutrons move between her sock and the carpet.
Protons move between her sock and the carpet.
All three particles move between her sock and the carpet.
Drag the correct sock to the box that describes the electric force that would occur between it and the towel.
The bear and the paper have electric charges causing them to attract. Select the amount of particles you need to add to the bear and to the cloth to make it so that these two objects will no longer attract OR repel.
bear 3 electrons and cloth 4 protons
bear 3 electrons and cloth 3 protons
bear 3 electrons and cloth 5 protons
bear 5 protons and cloth 3 electrons
Electric force is __________.
a type of force that can only occur when two objects come into contact

True
False

induction
static
conduction
conservation
friction
Select the arrows that correctly show the type of electric force between the two socks.
What is static electricity?
a buildup of charged subatomic particles on an object
a group of electrons which travel from the clouds to the ground during a thunderstorm
a loss of charge after static electricity builds up on an object
a type of energy created when two objects push against each other
Which diagram is correctly labeled?
Electric force can cause __________.
Check all that are true (choose 2).
objects to pull toward each other
objects to push away from each other
none of the above
objects to not be made of atoms
What is wrong with this picture?
Objects with similar charges repel each other instead of attracting each other.
Objects cannot have more positive particles than negative particles.
Objects with electric charge cannot attract.
Objects with any negative charges would always repel.
