1

What is the charge of an electron?

Negative (-)

2

Describe what happens to charges when you rub a balloon on your jumper.

Negative charges are transferred from your jumper to the balloon.

This leaves your jumper with a positive charge and the balloon with a negative charge.

Your jumper and the balloon will attract each other.

 

 

3

What is the charge of a neutron?

neutral (no charge)

4

Charged particles such as electrons have an invisible 'field' around them called an...

electric field.

5

A negative charge will ______ a negative charge.

repel

6

A positive charge will ______ a negative charge.

attract

7

Electrons can move freely through materials such as metals. We call materials like this...

Conductors

8

Identify the missing label.

9

A positive charge will ______ a positive charge.

repel

10

What does the diagram show?

The structure of a single atom.

11

Identify the missing label.

12

Electrons are trapped (cannot move) through materials like rubber. We call materials that do this...

insulators.

13

A negative charge will ______ a positive charge.

attract

14

Everything is made from particles called...

atoms

15

What is the overal charge of an atom?

Why?

Neutral

because they have the same number of protons and electrons so their charges cancel each other out.

16

Identify the missing label.

17

When charged particles such as electrons move through materials we call this an...

electric current

18

What are the 2 types of electric charge?

Positive (+)

Negative (-)

19

Do you see or hear thunder?

You hear it

20

Name the 3 particles that make up an atom

Proton

Electron

Neutron

21

What is the charge of a proton?

Positive (+)

22

Do you see or hear lightning?

You see it.

23

A charge particle has an invisible 'field' around it. What do we call this field?

An electric field.

24

What happens if you put a charged object in an electric field?

A force (push or pull) will act on it.
