Static Electricity Practice

What is the size comparison between electrons and protons?

• Electrons are 1000x larger than protons.

• Electrons are the same size as protons.

• Electrons are 1000x smaller than protons.

• Electrons are 10x smaller than protons.

Do protons jump from atom to atom?

• Yes, protons jump frequently.

• No, protons never jump from atom to atom.

• Protons sometimes jump.

• Protons jump only in certain conditions.

What happens to an atom when it loses an electron?

• It becomes negatively charged

• It becomes positively charged

• It remains neutral

• It becomes a neutron

What is the role of valence electrons in charging with friction?

• They determine the color of the object.

• They are involved in gaining or losing electrons.

• They make the object magnetic.

• They change the object's temperature.

What happens when you rub an object with low electron affinity against an object with high electron affinity?

• Both objects become positively charged.

• Both objects become negatively charged.

• Two charged objects are created.

• No charge is created.

Which material becomes positive due to low electron affinity?

• Silicon

• Plastic

• Cotton/Wool

• Rubber

Which material is associated with high electron affinity and becomes negative?

• Glass

• Human Body

• Plastic

• Cotton/Wool

What can static electricity interact with?

• Only charged objects

• Charged and Non-charged (neutral) objects

• Only metals

• Only liquids

What is static electricity?

• A type of electricity that flows easily

• A build-up of charges on objects that don't allow charges to move

• Electricity that is always in motion

• A form of electricity that powers devices

Why is copper used in electrical wiring?

• It is a good insulator

• It is a good conductor

• It is lightweight

• It is inexpensive
