In materials such as metals, the outer shell electrons are loosely bound to the nuclei of their atoms and are free to move from one atom to another. These materials are good conductors. Question 1 options: True False Question 2 (3.33 points) forces between charges are enormous in comparison to forces. Question 2 options: Electric, gravitational Gravitational, electric Positive, negative Negative, positive Question 3 (3.33 points) The two types of charges, positive and negative, are not created alone, but in pairs. Question 3 options: True False Question 4 (3.33 points) A/An is a material in which charges will not move easily, whereas a/an is a material that allows charges to move about easily. Question 4 options: conductor, insulator insulator, conductor electroscope, conductor insulator, electroscope Question 5 (3.33 points) Charges added to a conductor quickly spread over the surface of the object. Question 5 options: True False Question 6 (3.33 points) Electric charges exist within atoms. Question 6 options: True False Question 7 (3.33 points) Charges added on one part of an insulator remain on that part. Question 7 options: True False Question 8 (3.33 points) Metals contain electrons; rubber has electrons. Question 8 options: bound, free free, bound excess, insufficient insufficient, excess Question 9 (3.33 points) An area with excess electrons has a net charge; an area with a deficit of electrons has a net charge. Question 9 options: negative, positive positive, negative positive, neutral negative, neutral Question 10 (3.33 points) Like charges repel, whereas opposite charges attract. Question 10 options: True False Question 11 (3.33 points) Electric potential differences are measured in amperes. Question 11 options: True False Question 12 (3.33 points) An electric field is a field that exists around a , whereas electric field lines provide a model that indicates the field’s strength. Question 12 options: charg
