| Question | Answer |
| Identify the 3 subatomic particles of an atom? | Neutron, Proton and Electron
|
What are the charges on Neutron, Proton and Electron? | Neutral, Positive and Negative
| What are the relative masses of the subatomic particles? | Neutron = 1, Proton = 1 and Electron = 1/1836
| What is an isotope? | Same number of protons but different number of neutrons
| What is the name for group 1 elements and how many electrons do they have in their outer shell? | Alkali metals, 1 outer shell electron
| What is the name for group 7 elements and how many electrons do they have in their outer shell? | Halogens, 7 outer shell electrons
| What is the name for gourp 0 elements and how many electrons do they have in their outer shell? | Noble gases, full outer shell
| What happens to the reactivity of group 1 elements as you move down the group? | increases
| What happens to the reactivity of group 7 elements as you move down the group? | decreases
| What happens when an alkali metal reacts with water? | Metal hydroxide + Hydrogen
| What is ionic bonding? | Where a metal element transfers its electrons to a non-metal element to form full outer shells.
| What are properties of ionic lattices? | Strong bonds, Strong electrostatic forces of attraction, high melting and boiling points, can conduct electricity when molten or in solution as ions are free to move.
| What is covalent bonding? | Where non-metal elements share their electrons to have a full outer shell.
| What are properties of simple covalent molecules? | Strong bonds, Weak intermolecular forces, low melting and boiling point, cannot conduct electricity.
| Identify 3 giant covalent structures | Diamond, Graphite, Sand, Buckminster Fullerene
| Describe metallic bonding and why metals can conduct electricity | Positive metal ions surrounded by a sea of delocalised electrons, can conduct electricity as the delocalised electrons can move to carry the charge.
| What is an alloy? | A mixture of elements at least 1 is a metal, combined to change the properties such as strength
| What is a shape-memory alloy? | A smart material that can remember its original shape, when deformed if the material is heated it will return to its original shape.
| What is the process for polymerisation? | Small monomers added together to make a long chain polymer, double c=c bond is broken up to allow the addition of small molecules, process requires high pressure and temp. |
