Basic Concepts of Atomic Structure and Electricity

Which particles make up an atom?

• Protons, neutrons, and electrons

• Protons and neutrons only

• Electrons and ions only

• Neutrons and ions only

What is the atomic number of an element?

• The number of neutrons in an atom

• The number of protons in an atom

• The number of electrons in an atom

• The sum of protons and neutrons

What is an ion?

• An atom that has gained or lost a neutron

• An atom that has gained or lost an electron

• An atom with a neutral charge

• An atom with a positive charge only

What is an electrical conductor?

• A material that does not allow charge to pass through

• A material that allows charge to move easily through it

• A material that only conducts heat

• A material that only conducts sound

What is static electricity?

• Electricity that flows through a conductor

• Electricity caused by the rubbing together of two insulators

• Electricity generated by a battery

• Electricity that powers household appliances

How do charged particles behave?

• Like charges will attract, opposite charges will repel

• Like charges will repel, opposite charges will attract

• Like charges will attract, opposite charges will attract

• Like charges will repel, opposite charges will repel

What is the circuit symbol for a switch?

What unit is energy measured in?

• Watt (W)

• Volt (V)

• Joule (J)

• Ampere (A)

What is a series circuit?

• A circuit with multiple loops

• A circuit with only one loop

• A circuit where components are parallel

• A circuit that never stops working

What happens if one component breaks in a parallel circuit?

• The whole circuit stops working

• The rest of the circuit will still work

• The circuit will explode

• The circuit will short-circuit
