• nonmetals

• metals

• transition metals

• metalloids

The free sea of electrons in metallically bonded substances gives metals special physical properties. Which of the following is NOT a property of metals?

• Hard

• Can conduct electricity

• Very brittle (breaks easily)

• Malleable (can bend without breaking)

Which describes the behavior of valence electrons involved in metallic bonds?

• They stay on the metal atom.

• They are transferred from atom to atom.

• They form a covalent bond with another atom.

• They float around freely between all the metal cations that donated them.

What is meant by the term "sea of electrons"?

• It's what we call all the free floating electrons in a metal.

• It's what we call electrons that are floating in a liquid.

• It's the total number of electrons in a metal atom.

• It's the total number of electrons in the ocean.

Why are metals good conductors of electricity?

• The electric current can easily travel along the surface of the metal because it is smooth.

• A negative charge can easily push the sea of electrons in one direction, making a current.

• Metals attract electricity.

• Metals are malleable.

Why are metals malleable? (They can bend without breaking.)

• Metals are very smooth.

• Metals are always liquids.

• Metals are covalently bonded.

• Free electrons keep metal cations from repelling when pressed together

What do we call electrons that move freely in a metallic bond?

• sea of electrons

• lone electrons

• unpaired electrons

• covalent electrons

What property of metals is the image describing?

• malleable (bend w/o breaking) & ductile (stretch into wire w/o breaking)

• conductive (can conduct electricity)

• shiny

What is the one thing responsible for a metal being malleable, ductile, and conductive?

• metal atoms

• its covalent bonds

• its valence electrons

• its sea of free-floating electrons

Kind of bonds in the compound CO₂ which contains only two nonmetals: C and O.

• Ionic
• Covalent
• Polyatomic Ion 
• Metallic
