What are elements in the tall columns of the periodic table?
Representative elements
Why are elements in the tall columns of the periodic table called representative elements?
They follow a pattern for valence electrons.

What elements in the tall columns periodic table called?
The tall columns in the periodic table are called groups or families. Elements in the same group share similar chemical properties and have the same number of valence electrons. For example, Group 1 contains alkali metals, while Group 17 consists of halogens. Each group typically exhibits trends in reactivity and other characteristics down the column.

Why are elements in tall columns of periodic table called representative elements?
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.
What are the tall columns of the periodic table called?
Representative elements
Why are elements in the tall columns in the periodic table called 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.
What are representatives elements?
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
Why are two rows of the periodic table taken out?
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.
Why are elements in the tall columns called representative elements?
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.
