Bonding; Ionic, Covalent & Metallic

Giant Ionic Regular Lattice Structures

Description:

• between metals and non-metals 
• electrons are transferred foriming oppositely charged ions that are then attracted to each other 

Phrases to use:

• electrostatic forces of attraction between oppositely charged particles
• form regular structures
• have high melting and boiling points as have to break strong bonds 

Description:

• between non-metals 
• sharing of electrons 
• orbits (shells) held together by covelent bonds
• two types; simple or giant structures/molecules

Molecules to know:

• diamond 
• silicon - SiO2
• graphite 

Simple:

• weak intermolecular forces 
• forces of attraction are easily overcome 

Phrases to use:

• held together by a sea of delocalised electrons
