1. Introduction to the Periodic Table
The Periodic Table organizes elements based on increasing atomic number.
Elements are arranged into periods (horizontal rows) and groups (vertical columns).
2. Modern Periodic Law
"The physical and chemical properties of elements are a periodic function of their atomic numbers."
Proposed by Henry Moseley
Corrected the flaws in Mendeleev’s periodic table
, 3. Structure of Modern Periodic Table
Groups: 18 vertical columns
Periods: 7 horizontal rows
Blocks:
s-block: Groups 1 & 2
p-block: Groups 13–18
