Ionic compounds

• conduct electricity

• conduct heat

• are good insulators

• are shiny

• are ductile

Ionic compounds appear​ (a)  

• crystalline
• powdery
• gaseous
• shiny
• dense

Ionic compounds can break. This means that they are

• strong

• brittle

• shaky

• shiny

• malleable

Metals are ​ (a)   which means that they can be drawn out into wires and cylinders

• shiny
• conductive

How do chemists describe the valence electrons of metals?

• As an ocean of possibilities

• As electrons in the d sublevel

• As a sea of free floating electrons

• As a sea of free floating protons

What makes metals strong, malleable, and ductile?

• Their density

• Their high melting points

• Their sea of free-floating electrons

• Their positive charges

• Their ability to conduct electricity
