Atoms-Electricity

Question 1

What does the nucleus contain?

Answer 1

protons and neutrons

Question 2

What surrounds the nucleus (on the outside of an atom)?

Answer 2

electrons

Question 3

Protons have a _________charge

Answer 3

Positive ( + )

Question 4

Electrons have a _______charge

Answer 4

negative ( - )

Question 5

Neutrons have a ____________charge

Answer 5

neutral charge (neither positive nor negative)

Question 6

The center of the atom is called the __________________

Answer 6

nucleus

Question 7

What does the structure of an atom look like?

Answer 7

In the center is the nucleus which contains protons and neutrons. They are surrounded by electrons

Question 8

What is static electricity?

Answer 8

Electrons move to create a build up of a charge in an object.

Question 9

Like charges _______________

Answer 9

repel

Question 10

unlike charges

Answer 10

attract

Question 11

What are the three ways to make static electricity

Answer 11

1. friction
2. conduction
3. induction

Question 12

Friction

Answer 12

rubbing

Question 13

conduction

Answer 13

touching and electrons move

Question 14

induction

Answer 14

no touching. electrons rearrange in an object as a charged atom gets close

Question 15

static electricity occurs when________

Answer 15

there is an imbalance of positively and negatively charged atoms

Question 16

Negative electrons orbit a positively charged ____________________

Answer 16

nucleus

Question 17

All materials are made up of __________

Answer 17

atoms

Question 18

How does static electricity work?

Answer 18

With static electricity, the electrons on the surface steal electrons from other atoms and the extra electrons they stole make them negatively charged

Question 19

How does friction cause static electricity

Answer 19

You rub objects together and the electrons from one object transfer to the other.

Question 20

How does conduction work with static electricity?

Answer 20

The transfer of electrons from one object to another by touch
“con-touch-don”
(like when you touch a person and you zap them)

Question 21

induction

Answer 21

Occurs when charges in an uncharged object are rearranged due to the attraction or repulsion of charged particles which are NOT touching

Question 22

Conductors ___________

Answer 22

Let electricity (electrons) through easily

Question 23

What are examples of conductors?

Answer 23

metal, water, Earth

Question 24

Insulators ________________

Answer 24

Don’t let electricity (electrons) through

Question 25

What are examples of insulators?

Answer 25

wood, rubber, plastic, glass, fabric

Question 26

What are the different types of circuits?

Answer 26

series circuit
parallel circuits

Question 27

What is a circuit?

Answer 27

A circuit is a path for electrons (electricity)

Question 28

What is a series circuit

Answer 28

A series circuit has one path for electrons..

Disadvantages:
- If one bulb goes out they all go out
- they get dimmer as you add more bulbs.

Question 29

What are advantages of a parallel circuit?

Answer 29

If one bulb goes out the rest can stay on

The brightness stays the same when you add more bulbs

Question 30

What is a parallel circuit

Answer 30

More than one path
Wires are parallel

Question 31

What does a wiring diagram look like?

Answer 31

Question 32

What does the symbol for a closed circuit look like?

Question 33

What does the symbol for a closed circuit look like?

Answer 33

Question 34

What is a short circuit?

Answer 34

A short circuit occurs when too much electricity breaks an object

Question 35

What does a circuit breaker do?

Answer 35

In a circuit breaker, a switch shuts off when the electricity becomes too much

Question 36

What is a fuse?

Answer 36

a thin metal strip that melts if there’s too much electricity

Question 37

What is a ground wire?

Answer 37

With a ground wire, excess electricity goes into the ground.

Question 38

Ground wire diagram
