The groups in the periodic table go by a variety of different names: Another way to group elements is based on their shared properties (in some cases, these groupings do not correspond to the columns in the periodic table). Such groups includealkali metals, alkaline earth metals, transition ...
Classification based on Chemical Properties: Chemical properties are another important factor in classifying elementary forms. Elements can be categorized into different groups based on their reactivity, valence electrons, and other chemical characteristics. The periodic table is a visual representation of th...
