Strength and type of atomic bonding
Closely packed atoms, strong bonds, rigid structure
Atoms roll over each other but remain attracted
Atoms attracted but not bound, move freely with space
Atoms share electrons from outer shells
Primary bonds
Very strong, difficult to break down
Bonding via attraction of oppositely charged ions
A charged atom (positive or negative)
Secondary bonds
Addition of heat
Sea of delocalised electrons in metals
