Other Chemical Properties
?
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, 
?
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,

Block
?
The p-block is on the right side of the periodic table and includes elements from the six columns beginning with column 13 and ending with column 18. Helium, though being in the top of group 18, is not included in the p-block.p block   
?
The d-block is on the middle of the periodic table and includes elements from columns 3 through 12. These elements are also known as the transition metals because they show a transitivity in their properties i.e. they show a trend in their properties.d block   
Element Family
?
All post transition metals are placed in group number 13, 14 and 15 of periodic table. In fact, they are located between Transition Metals and Metalloids. Post transition metals have very poor mechanical properties.Post-​Transition   
?
What is Transition Metal? All transition metals are placed under the d-block from group number 3 to 12. Transition metals show characteristics like malleability, ductility and are good conductor of electricity.Transition Metal

Crystal Structure
?
Rhombohedral crystal lattice structure comes under trigonal crystal structure. The Rhombohedral crystal structure is a term associated trigonal crystal structure with the rhombohedral lattice.Rhombohedral (RHO)   
?
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)
