Metallic bond - common in transition metals where electrons become delocalized and move around collective positive nuclei. Thus, since electrons are allowed to slide over each other (not localized = free to move), these metals are flexible (malleable, ductile, etc)
It is the metallic bonding between atoms of the element which allows them to be hammered into different shapes and drawn into thin wires,i.e.,the bonding makes the the element malleable and ductile.
Carbon's special bonding ability allows it to form many different compounds.

When elements combine, the resulting compound is usually very different to the original elements. Take common salt for example. Sodium and chlorine are very reactive elements that you certainly would not allow anywhere near your food, yet sodium chloride is an essential part of our diets.
Potassium loses its one valence electron to form a cation with a +1 charge. This will allow it bond easily with non-metal anions to form an ionic compound with an ionic bond.
Vessel elements and Tracheary elements are part of the xylem. They connect end to end and allow for transport of water and minerals.
Supernatural elements are elements that are not readily found in the population. Psychics have supernatural elements in their genetic make-up that allow them to see things most people can't.
The alkali metals in group one are called unipositive because each atom allows one electron to move freely through out the bulk of the metal. This is know as the electronic sea. Group two atoms allow two electrons to move freely. The more electrons of each atom that is available for bonding the harder and more dense the structure.
Metallic bonding occurs between copper atoms. Only copper is a metal and has the characteristics needed for metallic bonding. Metallic bonding occurs between atoms with low electronegativities (low tendency to attract electrons from other atoms) and low ionisation energies (little energy required to remove electrons from the atoms). The low tendency for the metallic atoms to keep their electrons allow their electrons to be shared between the atoms, which thus become cations. The cations tend to be very closely-packed; they are not repulsed by their similar positive charges, but attracted to the electrons flowing freely between the cations. Metallic bonding therefore occurs between copper atoms, which have low electronegativity and ionisation energy. Chlorine atoms have some of the highest electronegativity and ionisation energy of all elements, and thus do not exhibit metallic bonding.
