How do ionic bonds form?
Electron pairs are shared between atoms.
Metal atoms lose electrons, which are gained by non-metal atoms.
Protons are exchanged.
Metal atoms lose their outer shell electrons.
What is an ionic bond?
A shared pair of electrons.
A strong intermolecular force of attraction between oppositely charged ions.
A strong electrostatic force of attraction between oppositely charged ions.
A strong electrostatic force of attraction between positively charged metal ions and negatively charged delocalised electrons.
Define the term ‘ion’.
A cation
An atom or group of atoms which has lost or gained electrons.
An anion
A charged molecule.
An ionic lattice structure:
Is a giant structure
Consists of a regular arrangement of ions.
Has delocalised electrons which can move.
Is held together by strong electrostatic forces of attraction.
A covalent bond is:
A shared electron.
A shared pair of electrons.
The strong electrostatic force of attraction between oppositely charged ions.
The strong electrostatic forces of attraction between positive metal ions and delocalised electrons.
A substance has low melting and boiling points. What kind of bonding is it likely to contain?
Giant ionic
Giant covalent
Giant metallic
Simple covalent
A substance has medium melting and boiling points and conducts electricity both as a solid and liquid. What is it’s bonding likely to be?
Giant covalent
Giant ionic
Giant metallic
Simple covalent
A substance has high melting and boiling points and only conducts electricity when molten or dissolved in solution. What kind of bonding is likely to be present in the substance?
Giant covalent
Giant ionic
Giant metallic
Simple covalent
A substance has high melting and boiling points, is very strong and doesn’t conduct electricity in any state. What kind of bonding is it likely to consist of?
Giant ionic
Giant covalent
Giant metallic
Simple covalent
Simple covalent structures have low melting and boiling points because:
Weak covalent bonds are broken
Strong covalent bonds are broken
Weak intermolecular forces of attraction are broken
Strong intermolecular forces of attraction are broken
Malleability is a property of metals which means they can be:
Pulled into wires
Bent/hammered into shape
Good conductors of electricity
Good conductors of heat
Ionic compounds are:
Malleable
Ductile
Shiny
Brittle
Metals are:
Shiny
Brittle
Dull
Malleable
Why is diamond so strong?
Shiny
Ionic bonds are very strong
Tetrahedral structure resists force in all directions
Metallic bonds are very strong
Graphite is slippery because:
Layers can slide over one another
Weak intermolecular forces of attraction exist between the layers
Covalent bonds are weak
Atoms are different sizes
