6.1 The Characteristics of Static Electric Charges

What happens when an atom gains electrons?

• It becomes positively charged.

• It becomes negatively charged.

• It becomes neutral.

• It loses protons.

What are electric charges?

• Charged particles that exert a force on each other

• A type of electrical circuit

• A charge that builds up on the surface of an object

• The tendency of a substance to hold on to electrons

What is the electric charge of a proton?

• Negative

• Neutral

• Positive

• No charge

Where are the electrons located in an atom?

• In the nucleus

• Outside the nucleus

• In both the nucleus and outside

• Electrons are not part of an atom

What makes an atom neutral?

• An equal number of protons and electrons

• An equal number of neutrons and electrons

• A greater number of protons than electrons

• A greater number of electrons than protons

What is the common cause of electron transfer?

• Law of Attraction

• Friction

• Law of Repulsion

• Static electric charge

Which of the following materials is listed as having a tendency to lose electrons in the Triboelectric Series?

• Amber

• Human skin (dry)

• Ebonite

• Teflon®

What is the effect of rubbing two objects together?

• It causes the objects to pull toward each other

• It generates heat only

• It causes the objects to become electrically charged

• It causes the objects to repel each other

What happens to the position of the positive charges when objects are rubbed together?

• They move to the object losing electrons

• They move to the object gaining electrons

• They are created

• They do not change

What happens when two objects made out of different materials are rubbed together?

• They both become positively charged

• They exchange electrons and one becomes negatively charged while the other becomes positively charged

• They both become negatively charged

• Nothing happens
