Metallic Bonding

What is the basis of a metallic bond?

• the attraction of neutral metal atoms.
• the attraction between protons and neutrons.
• the attraction between positive metal ions and interlocking electrons.
• the attraction between positive metal ions and free floating electrons.

At room temperature, most metals are

• liquid
• solid
• gas
• an alloy

What does malleable mean?

• able to be shaped
• will break easily
• can be used for wire
• is shiny

Which of these is NOT an alloy?

• bronze
• copper
• brass
• stainless steel

What is the ability of a substance to be pulled into a wire?

• Malleability

• Ductility

• Conductivity

• Solubility

Why do metals conduct

• They are shiny
• The electrons are held tightly within the lattice
• The electrons are delocalised and able to move
• The electrons are shared between two metal ions

A mixture of two or more metals is called:

• mixture
• solution
• compound
• alloy

Which of these are considered properties of metals? (choose ALL that apply)

• brittleness

• low melting point

• luster (shininess)

• malleability

• ductility

I can hit a metal with a hammer without the metal shattering because of its __________.

• Ductility
• Malleability
• Conductivity
• Lustrousness

Why are alloys generally used to make everyday objects?

• Alloys are often stronger and less active than pure metals.
• Alloys have higher melting point than pure metals.
• Alloys are less expensive to produce than pure metals.
• Alloys have ionic bonds instead of metallic bonds.
