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.

What does malleable mean?

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

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

Why does the melting point of metals increase across period 3, from Sodium (Na) to Aluminium (AI)?

• Size of atoms gets smaller

• Attraction force between nuclei and free electron increases

• Increased space between the valence electrons in the "sea"

• Increased number of valence electrons contributed to the "sea"

What is the ability of a substance to allow heat, sound, or electricity to flow through it?

• Malleability
• Ductility
• Solubility
• Conductivity

Why are metals malleable?

• They are shiny

• The electrons are held tightly within the lattice structure making it strong

• The electrons are delocalized and able to move between the atoms

• The electrons are shared between two metal ions and this holds the atoms together
