Ionic, Covalent, and 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.

There are more metals than non metals in the periodic table.

• True
• False

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 thin strand?

• 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
