Why are the elements in groups 1A-8A called the representative elements?

Answer 1

They follow a pattern for valence electrons.

Answer 2

S- and p- electrons fill in a regular repeating manner. Hence, elements in the s- and p-blocks have predictable patterns that represent a wide range of properties. Therefore, the s- and p-block elements are called the main-group, or representative, elements.

Non-metals, Alkali, Halogens

Answer 3

The elements in Groups 1A through 8A are called representative elements because they represent the majority of physical and chemical properties in the Periodic Table. They are a mix of liquids, solids and gases with various other properties.

Answer 4

The elements in groups 1A to 8A are called the representative elements because they represent a wide range of chemical properties and are involved in the majority of chemical reactions. They are also known as the main group elements as they occupy the main blocks of the periodic table.

Answer 5

Elements in groups 1A-8A are called representative elements because, as a group, they display a wide range of physical and chemical properties.
