Classification of Elements and Periodicity in Properties:
This section covers the modern periodic table and the periodic trends of elements. Topics include atomic and ionic radii, ionization enthalpy, electron gain enthalpy, electronegativity, valence, and oxidation states.
4
Chemical Bonding and Molecular Structure:
This is a crucial topic that extends beyond just inorganic chemistry, but a deep understanding of bonding is essential. It includes theories like VSEPR, valence bond theory, and molecular orbital theory, as well as concepts like hybridization, resonance, and dipole moment.
5
Coordination Compounds:
This sub-part focuses on complex compounds. Key topics include Werner's theory, IUPAC nomenclature, isomerism (cis-trans, ionization), bonding theories (Valence Bond Theory and Crystal Field Theory), magnetic properties, and the color of coordination compounds.
5
s-Block Elements:
This section deals with the alkali and alkaline earth metals (Groups 1 and 2). It covers their general characteristics, reactivity towards various substances, and the properties of their compounds
5
p-Block Elements:
This is a large and important section covering groups 13 to 18. It details the electronic configuration, general trends in physical and chemical properties, anomalous behavior of the first element in each group, and the preparation, properties, and uses of important compounds of these elements.
7
d- and f-Block Elements:
This section focuses on transition elements (d-block) and inner transition elements (f-block). It includes general characteristics, electronic configuration, and trends in properties like ionization enthalpy, oxidation states, and magnetic properties.
5
Principles of Qualitative Analysis:
This topic, also known as salt analysis, involves the identification of cations and anions. It's an experimental chemistry topic that requires an understanding of the reactions and principles involved in separating and confirming the presence of different ions.
6
Metallurgy (General Principles and Processes of Isolation of Elements):
This part covers the general methods of extracting metals from their ores, including topics like concentration, reduction, refining, and the principles behind these processes

Lesson 2: Group 1 Elements (Alkali Metals)

This lesson focuses on the detailed properties and compounds of lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and caesium (Cs).

Chemical Properties: Students will explore the reactivity of alkali metals towards air, water, and halogens. They are highly reactive and form oxides, peroxides, and superoxides with oxygen. Their reaction with water is vigorous, producing hydrogen gas and hydroxides.
Anomalous Behavior of Lithium: Lithium, the first element of the group, exhibits unique properties due to its very small size and high polarizing power. This is called the diagonal relationship with magnesium. Key differences include the formation of a simple oxide, its greater hardness, and the thermal instability of its carbonate and nitrate.
Important Compounds: Students will study the preparation, properties, and uses of key compounds like:
- Sodium Carbonate ( $N a_{2} C O_{3}$ ): Preparation by the Solvay process and its use in glass and soap manufacturing.
- Sodium Hydroxide ( $N a O H$ ): Preparation by the Castner-Kellner process and its use in a variety of industries.
- Sodium Chloride ( $N a Cl$ ): Its importance as a common salt.
Biological Importance: Sodium and potassium ions play crucial roles in biological systems, such as in nerve signal transmission and maintaining the osmotic balance in cells.
