Atoms and Matter
All matter is made up of?
Atoms
Protons have a
1. Positive Charge
2. Negative Charge
3. No Charge
Positive charge
An object had 4 protons and 7 electrons. It is considered
electrically charged
negatively charged
Electrons move easily between materials when we rub them together. True or False?
True, causes an accumulation of charged particles
What is a electrical conductor?
An object that electrons move easily from one atom to another.
Atoms have 2 parts. What are they?
A nucleus and subatomic particles
Neutrons have
1. Positive Charge
2. Negative Charge
3. No Charge
No charge
An object has 462 protons and 352 electrons. It is considered
When two objects have opposite electric charges they
Attract (come together)
What is a electrical insulator?
Materials that don't let electric current pass through
Where is the nucleus located?
The middle
Electrons have a
1. Positive Charge
2. Negative Charge
3. No Charge
Negative charge
An object has 62 protons and 62 electrons. It is considered
Electrically neutral
When two objects have the same electric charge they
Repel (pull apart)
What is an example of a electrical conductor?
Metal and wires
What is the nucleus made up of?
Protons and neutrons
When an object contains the same amount of electrons and protons it is
Electrically neutral
An object has 16 electrons and 14 protons. It is considered
Electrically charged
Negatively charged
What is electric current?
The flow of of electrons between atoms. Flowing through a wire is a prime example
What is an example of a electrical insulator?
Wood, glass and plastic
Do electrons stay still or move around the nucleus?
Electrons revolve around the nucleus and are constantly moving
When an object contains different amounts of protons and electrons it is considered
Electrically charged
What is static electricity?
Accumulation (pile up) of charged particles, either positive or negative
Where can electricity be generated?
In power plants.
Electric energy can be produced by the wine, water, or burning fossil fuels such as coal and petroleum
When is a magnetic field produced?
When electric current flows through wires
