C2
Ions
Ionic Compounds
Ionic compounds have a regular lattice structure
All have similar properties
conductive when aqueous or liquid
dissolve easily
high melting and boiling point
Empirical formula to calculate amount of each ion
Ions are charged particles
They can be single atoms or groups of atoms
metals lose electrons and form positive ions
non-metals gain electrons and form negative ions
Ionic bonding is the transfer of electrons to form bonds between ions
Groups 1&2 and 6&7 are the most likely to form ions
Use dot and cross diagrams to represent ionic bonding
Covalent Bonding
How non-metals bond
Happens when non-metals share electrons
Use dot and cross diagrams
Most gases are covalently bonded to each other to become diatomic
simple covalent structures have similar properties
low melting & boiling point
non conductive
Giant covalent structures
have similar properties
High melting and boiling point
hard and brittle
Allotropes of carbon
Diamond
Graphite & Graphene
Buckminsterfullerene
Macromolecules
Polymers are long repeating Hydrocarbon structures
Tend to be in between Simple and Giant Covalent Structures in terms of properties
Metallic bonding
Between metals
Most metals are solid at room temperature
Layers of Nuclei with a see of freely moving electrons to hold layers together
Good conductors
Malleable
Alloys
Combine properties of the metals they are made of
Nanoparticles
Very small particles
large surface area to volume ratio
very useful in medicine and engineering
Used in suncreams, antiseptics and to deliver drugs
Used for conducting electricity in iny circuits
Act as catalysts for reactions
States Of Matter
Solid
Liquid
Gas
Aqueous
Can change from on to another through changes in state (addition or reduction of energy)
