| metallic bonding -description | a lattice of metal ions(cations) surrounded by a sea of delocalised electrons |
| covalent bonding-description | occurs whenever electrons are shared between two elements |
| ionic bonding | occurs when there is a complete electron transfer from one element to another |
| a polar bond | between H and Cl in HCl |
| a non-polar molecule with polar bonds | O=C=O |
| a molecule with non-polar bonds | O=O |
| a polar molecule that does not show H-bonding between molecules | H2S |
| an example of a covalent layer lattice | graphite |
| an example of a covalent network lattice | SiO2 |
| diamond | an allotrope of graphite |
| graphite | has layers of carbon rings held together by delocalised electrons |
| a molecule with tetrahedral symmetry | CH4 |
| substances containing this bonding will conduct electricity in their solid state | metallic bonding |
| substances containing this bonding will conduct electricity only in molten or dissolved state | ionic bonding |
| substances with this bonding will not conduct electricity in any state | covalent bonding |
| metallic bonding-example | Mg(s) |
| ionic bonding-example | Na2CO3 |
| a mixture of metals(or sometimes C) | alloy |
| an example of an alloy | bronze |
| a substance where the molecules are held together by hydrogen bonding | NH3 |
| CO2 | a linear molecule |
| H2O | a V-shaped molecule |
| Hydrogen bonding occurs between molecules that have hydrogen bonded to... | F, O or N |
| the bonding within a molecule | intramolecular bonding |
| the bonding between molecules in a solid or liquid | intermolecular bonding |
| electronegativity | the electron-attracting power of a particular element |
| the most significant type of intermolecular bonding between HBr molecules | dipole-dipole interaction |
| the only type of bonding possible between non-polar molecules | dispersion forces |
| as molecules get larger the size of the dispersion forces... | increases |
| dispersion forces | bonding between water molecules consists of hydrogen bonding and... |
