Elements in the tall columns of the Periodic Table are called representative elements because they exhibit a wide range of physical and chemical properties that are representative of the overall characteristics of the elements in their respective groups. These elements include groups 1, 2, and 13-18, which display predictable behaviors in bonding and reactivity due to their valence electron configurations. Their diverse properties make them key examples for understanding the trends and patterns within the periodic table.
They follow a pattern for valence electrons.

Elements in the tall columns of the periodic table, known as representative elements, are called so because they exhibit a wide range of chemical and physical properties that are representative of the broader trends in the periodic table. These elements include groups 1, 2, and 13-18, which display predictable patterns in their valence electron configurations and reactivity. Their behavior and characteristics make them ideal for illustrating the principles of periodicity and element classification.
The tall columns of the periodic table are called groups or families. Elements in the same group share similar chemical properties due to having the same number of valence electrons. For example, the alkali metals in Group 1 are highly reactive, while the noble gases in Group 18 are inert. Each group has a unique set of characteristics that define its elements.

The elements in tall columns are called capital, shaft, and base. The capital is the decorative top portion, the shaft is the long vertical section, and the base is the bottom part of the column.
Conventionally representative elements are called the chemical elements from the groups 1,2, 13-18. These elements haven't generally variable valencies. The transitions metals are not representative elements.

elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
