Which statement describes the lattice structure of a metal?
The lattice consists of alternating positive ions and negative ions.
The lattice consists of neutral atoms arranged in layers.
The lattice consists of positive ions in a ‘sea of electrons’.
The lattice consists of neutral atoms in a ‘sea of electrons’.
The diagram shows metallic bonding.
Which labels are correct?
X: atomic nucleus
Y: outer electron
X: metal atom
Y: mobile electron
X: metal cation
Y: mobile electron
X: positive ion
Y: negative ion
The diagram represents the general structure of a solid Z.
What is Z?
aluminium
iodine
silicon dioxide
sulfur
Which substance exists as a lattice of positive ions in a ‘sea of electrons’?
liquid potassium chloride
solid graphite
solid magnesium
solid silicon(IV) oxide
X is a solid at room temperature.
X has a high melting point.
Solid X conducts electricity.
Which diagram shows how the particles are arranged in solid X?
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 moving electrons.
Why do metals conduct electricity?
They are shiny
The electrons are delocalised and able to move
The electrons are held tightly within the lattice
The electrons are shared between two metal ions
Why do metallic compounds conduct electricity as solids?
core electrons are mobile, allowing electricity to flow through the metal
valence electrons are mobile, allowing electricity to flow through the metal
protons are mobile, allowing electricity to flow through the metal
the metal cations are mobile, allowing electricity to flow through the metal
Metals are good conductors of heat...
because they are shiny and reflect heat.
because the absorb heat.
the electrons are delocalised and able to move, colliding with cations to transfer themal energy.
because the cations can move freely to transfer thermal energy.

What does a metallic bond consist of?
Forces between metal ions and delocalised electrons
Pairs of metal atoms joined together by strong bonds
