Question

Define P block elements in Modern Periodic Table

Answer 1

Part 1: Modern Periodic table

• The modern periodic table is an arrangement of all the elements known in accordance with their increasing atomic number and recurring chemical properties.
• It is a tabular display of 118 chemical elements which consists of horizontal rows called periods and vertical columns are called groups.
• It consists of s, p, d, and f block elements

Part 2: P block elements :

• P block starts from the 13^th group and goes to the 18^th group in the periodic table.
• P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells.
• The p-subshell has three p-orbitals each of which can accommodate a maximum of two electrons, therefore there are six groups of p-block elements.
• In p block metals, non-metals, and metalloids are found simultaneously.
• They include the boron, carbon, nitrogen, oxygen, fluorine families, and noble gases.
