Ionic bonding
Metal and non metal
Transfer of electrons
Covalent bonding
Non metals
Sharing electrons
Metallic bonding
1 metal
Positive ions in a sea of delocalised electrons
Ion
A charged particle formed when an atom gains or loses electrons
Cation
Positive ion
Cat has pos
Anion
Negative ion
Molecular ion
A charged particle containing two or more atoms covalently bonded
What is an ionic bond
The attraction between oppositely charged ions
Diatomic
Two atoms covalently bonded in the molecule
What is metallic bonding
The attraction between delocalised electrons and the positive ions in a regular lattice
When is the sign in the corner a plus
When it loses electrons
When is the sign in the corner a negative
When it gains electrons
What is a structural formula
Another way of writing a covalent bond
Eg fluorine: F-F
Or O=C=O
Amount of electrons shared is shown with the number of lines
