Question

What are typical or representative elements in the modern periodic table?

Answer 1

• The modern periodic table is an arrangement of all the elements known by their increasing atomic number and recurring chemical properties.
• It is a tabular display of a total of 118 chemical elements which consists of horizontal rows called periods and vertical columns are called groups.

Typical elements:

• The periodic table is divided into separate blocks i.e. s,p,d, and f.
• The typical elements are present in the s and p blocks.
• The elements of third-period are called typical elements or representative elements
• They are called typical elements or representative elements because they represent the properties of their group without anomalies.
• The chemical and physical properties of all the elements of a group can be studied by studying the properties of the representative element of that group.
• The typical elements consist of eight elements as follows:

1. Sodium
2. Magnesium
3. Aluminum
4. Silicon
5. Phosphorus
6. Sulfur
7. chlorine
8. Argon
