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   
?
Stable metals are non radioactive metals and have zero valence electrons in the outer shell.Chemical Stability,

Block
?
The f-block is in the center-left of a 32-column periodic table but in the footnoted appendage of 18-column tables. These elements are not generally considered as part of any group. They are often called inner transition metals.f 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   
Element Family
?
Total 15 metals are included in actinide series, from Actinium to Lawrencium. Actinide series is located under f and d block of the periodic table.Actinide
