Which of the 3 subatomic particles moves easily and is responsible for the formation of electricity charges and current?

• proton

• neutron

• electron

A balloon starts of with a neutral charge (5 protons, 5 electrons), and GAINS 3 more electrons.

What is the new overall charge of the balloon?

• positive

• negative

• neutral

A sweater starts of with a neutral charge (5 protons, 5 electrons), and LOSES 3 electrons as a balloon is rubbed on it.

What is the new overall charge of the sweater?

• positive

• negative

• neutral

How are static electricity charges formed?

• through the imbalance of positive and negative charges

• through movement of negative charges

• through the transfer of energy from mechanical to electric

• through the refraction of electrons through a conductor

How is current electricity formed?

• through the imbalance of positive and negative charges

• through movement of negative charges

• through the transfer of energy from mechanical to electric

• through the refraction of electrons through a conductor

How are electrons involved in the formation of magnetic objects?

• the object's electron spin and orientation

• the balance of positive and negative charges

• the movement of electric charges

What is the rule of attraction/repulsion for ELECTRIC charges?

• opposites attract, likes repel

• opposites repel, likes attract

• electric charges do not attract or repel, only magnets do
