Answer 21

ion with inbalance protons and electrons

Question 22

negative (nonmetals become anion)

Answer 22

Anion

Question 23

Question 24

is a list of common materials that were experimented or found to behave in
a predictable way

Answer 24

Triboelectric series

Question 25

are substances that have free electrons and allow charges ( e ) to move freely through them

Answer 25

Conductors

Question 26

-the accumulation of electric charge on a surface of or within a material - the shock happens when the extra electrons move and are released or discharged from an object - the charge doesn't have to be moving, its still there even its resting on an object example of electrostatic force:

Answer 26

Static Electricity

Question 27

is a material electrons can easily travel across

Answer 27

Conductor

Question 28

like car tire, a material that resists the movement of charge

Answer 28

Insulator

Question 29

that ranks materials on how easily they give up or receive electrons

Answer 29

Triboelectric series

Question 30

is one way that objects can accumulate an electrostatic charge

Answer 30

friction

Question 31

the transfer of charge by direct contact

Answer 31

Conduction

Question 32

a device that shows how charge accumulates, it has metal sphere on the top connected to two metal foil leaves at the bottom by a metal rod, the leaves will either repel each other or attract depending on the charge they are given

Answer 32

Electroscope

Question 33

charging a neutral object by bringing a charged object closed to but not touching the object

Answer 33

Induction

Question 34

droplets suspended in the air

Answer 34

Aerosol

Question 35

- gigantic electrostatic machines -can capture up to a large percentage of the particles from the burning material though some pollution does escape -that first charge dirt particles negatively and then capture them on a positively charged plate where they can't escape into the air

Answer 35

Precipitators

Question 36

states that electric charge cannot be created or destroyed but can be transferred from one object to another

Answer 36

Law of conservation of charge

Question 37

is conservative, that means it cannot be created or destroyed

Answer 37

electrostatic force

Question 38

s a form of electricity in which charge rests on an object until another charge makes it move

Answer 38

Static electricity

Question 39

- is the attraction between attraction or repulsion of electrons and protons -some materials are insulators and some are conductors -objects can accumulate charge by friction, induction, conduction

Answer 39

Electrostatic force
