Conductors, Insulators, and Semiconductors

This type of material allows current to flow easily:

• Insulator

• Conductor

• Semiconductor

• None of the above

These are strong bonds typically found in insulators like plastic. They involve equal sharing of electrons between two atoms.

• Metallic bond

• Ionic Bond

• Covalent Bond

NGSS.HS-PS1-1

This element is typically added to silicon to make a p-type semiconductor due to the fact that it has 3 valent electrons.

• Phosphorus

• Fluorine

• Nitrogen

• Boron

Why are metals like copper good conductors?

• They have covalent bonds

• They are shiny

• The valence shells of neighboring copper atoms overlap.

• The valence electrons are tightly bound to the nucleus.

NGSS.HS-PS1-1

This element is commonly used to make n-type semiconductors since it has 5 valence electrons

• Boron

• Carbon

• Phosphorus

• Oxygen

This semiconductor device is made by combining a single p-type semiconductor with a single n-type semiconductor.

• Transistor

• Diode

• Photoresistor

• Logic Gate

This feature of pn-junctions is directly related to causing LEDs to have a forward voltage

• Depletion Zone

• No cell-phone zone
