Resumo de Recurso
C2 bonding
Ionic bonding
between metals and non metals
Forms + and - ions
Forms ionic compounds
Giant ionic lattices
Strong electrostatic forces of attraction
High melting and boiling points
Can dissolve in water
ions free to move conduct electricity
Covalent bonding
Between 2 non metals
simple molecular substances
weak inter molecular forces between molecules
Very low melting/ boiling points to separates the molecules
don't conduct electricity no ions so no electrical charge
Giant covalent structures
Examples
Graphite
good conductor
3 covalent bonds
each carbon atom 1 delocalised electron.
layers free to slide over each over. week intermolecular forces between layers
silicon dioxide
Diamond
each carbon 4 covalent bonds
very rigid and strong
Very high melting and boiling points
sharing electrons
Very strong bonds
Metalic structures
Alloys harder than pure metals
different elements have different sizes.
distort layers of metal atoms
giant structure
electrons delocalise
allow the layers to slide over each over
electrostatic attraction. positive metal ions + negative electrons
conducts heat + electricity
Isotopes
Different atomic forms of the same element. Same number of PROTONS different number of neutrons
