The energy structure of a crystal is characterized by continuous energy bands and energy gaps. The ability of a solid to conduct electricity relies on the energy structure of the solid

It is an extension of molecular orbital theory, where large numbers of atomic orbitals mix together to form very closely spaced groups of molecular orbitals called bands.

The retina in your eye, for example, is a transducer that converts photons into an electrical nerve impulse; your eardrum is a transducer that converts sound waves into a different electrical nerve impulse. A photon transducer takes a photon and converts it into an electrical signal, such as a current, a change in resistance, or a voltage.

To account for this freedom of movement modern theories of metallic bonding assume that the valence electrons are completely delocalized; that is, they occupy molecular orbitals belonging to the metallic crystal as a whole. These delocalized electrons are often referred to as an electron gas or an electron sea.

Its stable tetrahedral configuration makes it incredibly versatile and is used in various way in our every day lives. Found in everything from spaceships to synthetic body parts, silicon can be found all around us, and sometimes even in us.

Melting and boiling points rise across the three metals because of the increasing number of electrons which each atom can contribute to the delocalized "sea of electrons". The atoms also get smaller and have more protons as you go from sodium to magnesium to aluminum.
