Answer 5

Benjamin Franklin

Question 6

Discovered electrons (negative charge)

Answer 6

JJ Thomson

Question 7

Discovered protons (positive charge)

Answer 7

Ernest Rutherford

Question 8

Charges are measured in

Answer 8

Coulombs

Question 9

Occurs when an external charge sphere is placed near the neutral sphere; attraction occurs

Answer 9

Charge separation

Question 10

Has same amount of protons and electrons

Answer 10

Neutral sphere

Question 11

An objects sum of the number of electrons and protons

Answer 11

Net charge

Question 12

Chemical property of an atom to attract electrons itself

Answer 12

Electron Affinity

Question 13

Ranks materials based on their tendency to acquire charge

Answer 13

Triboelectric series

Question 14

This charge particle has the ability to transfer from one object to another

Answer 14

Electrons

Question 15

Electrons are transferred when objects are rubbed against one another

Charging by rubbing

Answer 15

Charging by Friction

Question 16

States if the object is neutral, negatively charged, or positively charged

Answer 16

Net charge

Question 17

It allows the flow of charges, especially electrons

Answer 17

Conductors

Question 18

It resists the flow of electrons

Answer 18

Insulators

Question 19

Atoms are made up of three subatomic particles namely:

Answer 19

Protons, electrons, and neutrons

Question 20

Unlike charges

Answer 20

Attract

Question 21

Like charges

Answer 21

Repel

Question 22

A charged object is touched to a conductor

Charging by contact

Answer 22

Charging by conductor

Question 23

Explain charging by conduction

Answer 23

When a good sphere conductor is placed near a negatively charged rod, electrons will then move from rod to sphere. After separation, both will obtain negative charges.

Question 24

Happens due to induced charges. No contact between two materials

Answer 24

Charging by induction

Question 25

Explain charging by induction

Answer 25

The charges in a conducting object can be rearranged with the presence of an external charged object.

Question 26

Two methods of charging an object

Answer 26

1. Charging by Friction 2. Charging by induction

Question 27

Can happen when you rub two objects with unequal electronegativity. The object with higher electronegativity will be negatively charged, and the other object with lower electronegativity will be positively charged.

Answer 27

Charging by Friction

Question 28

The algebraic sum of all the electric charges in any closed system is constant The charge is being conserved; cannot be created nor destroyed

Answer 28

Law of Conservation of Charge

Question 29

Changes in charges are brought by the movement of

Answer 29

Negatively charged particles
