What are typical elements in a periodic table?

Typical elements in the periodic table are the elements found in groups 1, 2, and 13 to 18 (excluding hydrogen and sometimes noble gases). They are also known as representative elements and belong to the s-block and p-block of the periodic table.

Groups of Typical Elements:

• Group 1: Alkali metals (e.g., Lithium, Sodium)
• Group 2: Alkaline earth metals (e.g., Magnesium, Calcium)
• Groups 13 to 18: Includes Boron family, Carbon family, Nitrogen family, Oxygen family, Halogens, and sometimes Noble gases

Characteristics of Typical Elements:

• Show a wide range of chemical and physical properties
• Include metals, nonmetals, and metalloids
• Exhibit variable valency and bonding types (ionic or covalent)
• Undergo predictable chemical reactions
• Have completely or partially filled outermost s or p orbitals
