Metallic Bonding

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

In metallic bonding, the strength of the bond is primarily determined by:

• The size of the metal ions.

• The charge of the metal ions.

• The number of delocalized electrons.

• The electronegativity of the metal atoms.

In metallic bonding, what are the electrons described as being?

• Transferred completely from one atom to another

• Shared equally between atoms

• Delocalized or free to move

• Paired in a hydrogen bond

In which of the following scenarios would you most likely find metallic bonding?

• Between two oxygen atoms

• In a piece of sodium chloride crystal

• In a pure gold ring

• In a water molecule

What is the primary reason metallic bonds are good conductors of electricity?

• The ions are free to move.

• The delocalized electrons can move freely.

• The covalent bonds allow electrons to move.

• The hydrogen bonds create pathways for electricity.

What type of bond involves the delocalization of electrons among a lattice of metal atoms?

• Ionic bond

• Covalent bond

• Metallic bond

• Hydrogen bond

Which of the following properties is characteristic of metallic bonding?

• Low melting point

• High electrical conductivity

• Low thermal conductivity
