Metallic character is the name given to the set of chemical properties associated with elements that are metals. Most metals are malleable and ductile and can be deformed without breaking. Metallic character decreases as you move across a period in the table from left to right. Metallic character increases as you move down an element group in the periodic table. Hydrogen is exception, which is a non-metal under ordinary conditions. Even hydrogen behaves as a metal when it’s a liquid or solid.
Elements with metallic character occur in certain groups or columns of elements, including the alkali metals, alkaline earth metals, transition metals (including the lanthanide and actinides). Some elements which shows metallic character are listed below.
- franium (element with highest metallic character)
- caesium (next highest level of metallic character)
