?
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,

Element Family
?
All alkali metals are placed under group number 1 and s-block of periodic table. These metals are highly reactive and are found in ores of other metals and minerals. Alkali metals can be easily distinguished from others as these metals have only 1 electronAlkali   
?
All alkaline earth metals are placed under group number 2 and s-block of periodic table. These metals are somewhat reactive at standard conditions. Alkaline earth metals appear shiny, silvery-white and are found in the earth’s crust.Alkaline Earth

Crystal Structure
?
BCC is a basis type of cubic crystal structure. In crystallography, the cubic crystals structure is a crystal system where the unit cell has a cube shaped structure. This is one of the simplest crystal structure found in crystals of metal.Body Centered Cubic (BCC)   
?
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)
