Other Chemical Properties
?
Stable metals are non radioactive metals and have zero valence electrons in the outer shell.Chemical Stability, 
?
Corrosion is a process which converts refined metals to their more stable forms, for example, its oxide and hydroxide. This process of metals getting corroded is a gradual destruction of metals by chemical reactions.Corrosion, 
?
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes.Ionization, 
?
Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.Solubility

Radioactive metals emit particles and radiation from their nuclei. This process comes in the picture because their nuclei experience the intense conflict between two strong forces. This metal also have radioactive isotopes.Radioactive Isotopes

Ductility of metals defines their ability to deform under tensile stress; this is often characterized by the metals ability to be stretched into a wire.Ductile, 
?
Malleability of metals defines their ability to deform under compressive stress; this is often characterized by the metals ability to form a thin sheet by hammering or rolling.Malleable,

Crystal Structure
?
In crystallography, the cubic (or isometric) crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals.Face Centered Cubic (FCC)
  
?
The hexagonal crystal system consists of the 7 point groups such that all their space groups have the hexagonal lattice as underlying lattice. The hexagonal crystal family consists of the 12 point groups such that at least one of their space groups has theHexagonal Close Packed (HCP)
