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,

?
The s-block is on the left side of the periodic table that includes elements from the first two columns, the alkali metals (group 1) and alkaline earth metals (group 2), plus helium.s 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
?
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   
?
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
