What is diatomic?
diatomic is when a molecule is made up of 2 atoms.
What is an ionic bond?
An ionic bond is the attraction between positive and negative ions.
What type of elements make up and ionic bond?
Metal and non-metals
what type of elements make up a Covalent bond?
Non-metals
What type of elements make up a metallic bond?
Metals
what are the bonds held together in a covalent bond?
Attraction of 2 positive nuclei for a shared pair of negative electrons.
What are the bonds held together in a ionic bond?
Attraction between positive and negative ions
What are the bonds held together in a metallic bond?
Attraction between positive metal ions and negative delocalised electron
Name the structure of an ionic compound?
Lattice
Name the structure of a covalent conpound?
covalent molecular and covalent network
Name the types of particles which make up an ionic lattice?
positive and negative ions
Whats this called?
Linear
Whats this called?
Angular
Whats this called?
Trigonal pyramaid
Whats this called?
Tetra hedral
Whats a molecule?
Small group of atoms covalently bonded together
Monotomic means not bonded so would not be in a compound.
If a compound is colourless then no ion in that compound has a colour
If a compound is coloured then at least one of the ions are coloured
what is electrolysis? 
electrolysis is the flow of electricity through ionic solutions to break up the ionic compound
Why do atoms bond?
to become stable
Covalent bonds can be described as a shared pair of electrons
Covalent molecular substances are made up of individual MOLECULES held together by forces of attraction.
Monatomic structures can only exist in noble gases
ionic compounds form a LATTICE structure containing millions of ions.
What holds the ions together?
The electrostatic attraction between positive and negative ions
Carbon (in the form of diamond and graphite), Boron and silicon are the only elements which form covalent networks.
