The elements in the tall columns of the Periodic Table, also known as groups or families, share similar chemical properties due to their comparable valence electron configurations. For example, Group 1 elements, such as lithium and sodium, are alkali metals known for their high reactivity, while Group 17 elements, or halogens, like fluorine and chlorine, are highly electronegative and reactive nonmetals. Each group has distinct characteristics that influence their reactivity, bonding behavior, and overall chemical behavior.

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.
Look what column it is in within the Periodic Table. The first column has 1 valance electron. The second column has 2 valence electrons. The entire section of shorter columns (all metals) also have two valence electrons. The tall column after that (with Boron ) has three valence electrons. The tall column after that (with carbon) has four valence electrons. This pattern continues until you reach the final column, the noble gasses (eg. Neon, argon, xenon); these all have 8 valence electrons.

Representative elements
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.
Representative elements
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
The two rows at the bottom of the periodic table are taken out to make the table more compact and easier to read. These two rows are known as the lanthanides and actinides series. They are removed and placed below the main table to avoid making the entire table wider than it is tall.
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.
