metals, aluminium/copper, type of bonds metallic it is strong.

# data[].attributes.body
the outer electrons become delocalised in a metal.

# data[].attributes.body
Simple moleculrs, most polymers, and substances with a giant covalent structure do not conduct electricity because they have no delocalised electrons.

# data[].attributes.body
metals are packed in a giant metallic lattice.

# data[].attributes.body
Metals condict electricity in its solid and liquid state because their delocalised electrons are free to move thought the lattice.

# data[].attributes.body
a metallic structure extends in three dimensions, and its metallic bonding extends in all directions.

# data[].attributes.body
simple molecules  and polymers have different properties depending on the strength of intermolecular forces, if the molecules are arraged in a lattice they may be brittle iodine crystals and some polymers are like this. But if the molecules are not arranged in a lattice, the substance may be soft or flexible.

# data[].attributes.body
giant covalent structures contain a lot of non-metal atoms, each joined to adjacent atoms by covalent bonds. Very high melting point, because a lot of strong covalent bonds must be broken. the atoms are usually arranged into giant regular lattices- extremely strong structures because of the bonds involved

# data[].attributes.body
simple molecules
hydrogen, oxygen,water and carbon dioxide all as simple molecules which is a non-metal and joined each other by covalent bonds.
a simple molecules is a molecules that only contains a few atoms .
these forces is easily broken.

ionic lattice is a metal and reacts to a non-metal
ionic bonds are strong electrostatic forces of attraction between oppositely charged ions.
ionic compounds is in the liquid state or dissolved in a solvent such as water plus ionic compounds conduct electricity when molten or in solution but not when they are in the solid state.

Try to match the bulk properties of each type of substance  with its structure.
