Molecular Structure Of Metals

4 Sep 2014. In a metallic solid atoms are arranged in a lattice-like 3D structure where there is a regular array of metal cations surrounded by a sea of delocalised electrons. In iron, the atoms are arranged in a lattice.

. the two main categories of solids: crystalline and amorphous. It then describes the four types of crystalline solids: molecular, network, ionic, and metallic. A look at different solids makes clear how atomic and molecular structure drives function.

Metals have a distinct bonding known as metallic bonds, where there is a sea of delocalised electrons and metal ions present. This is due to electrons leaving the atom forming a positive metal ion and a sea of delocalise electrons.

Moreover, in metals the bonding molecular orbitals (known as the valence band) are able to accommodate more electrons. or deformed, the atoms can move relative to one another, but the electrons remain spread throughout the structure.
