Charges and their transfer

Protons have ​ (a)   electric charge. Electrons have ​ (b)   electrice charge. Neutrons have ​ (c)   electric charge.

• positive
• negative
• no

Most atoms are electrically ​ (a)   because the number of protons equals the number of electrons. Atoms with an electric charge become charged by gaining​ (b)   ​ . When this charge becomes built up on an object, we call that build-up ​ (c)   .

• Neutral
• electrons
• static electricity
• posistive
• protons
• negative
• conduction
• grounding

There are three basic rules of electric charge. Opposite charges ​ (a)   , like charges ​ (b)   .

• attract
• repel

During a lab a balloon was rubbed with a wooly fabric. This is an example of which type of charging?

• conduction

• friction

• induction

Which of the following is caused by static electricity?

• a stove getting hot when it is turned on
• a magnet being attracted to a refrigerator
• a lightning strike during a storm
• a light bulb coming on when a switch is turned on

the negatively charged particle in an atom, moves freely, can be released, shared, or “stolen” from an atom

• proton

• neutron

• electron

the charging of an object by the contact of a charged object to a neutral object (like touching a door knob)

• induction

• conduction

• friction

what is the difference between a conductor and an insulator?

• a conductor allows electricity to flow through it easily and an insulator does not.

• an insulator allows electricity to flow through it easily and a conductor does not.

• a conductor is magnetic and an insulator is not.

• an insulator is magnetic and a conductor is not.
