Note: All chemical processes/reactions should be studied with reference to the reactants, products, conditions, observations and the (balanced) equations and diagrams.
1. Periodic Properties and variations of Properties โ Physical and Chemical
(i) Periodic properties and their variations in groups and periods.
Definitions and trends of the following periodic properties in groups and periods should be studied: atomic size; metallic character; non-metallic character; ionisation potential; electron affinity; electronegativity.
(ii) Periodicity on the basis of atomic number for elements.
The study of modern periodic table up to period 4 (students to be exposed to the complete modern periodic table but no questions will be asked on elements beyond period 4 โ Calcium); Periodicity and other related properties to be explained on the basis of nuclear charge and shells (not orbitals).
(Special reference to the alkali metals and halogen groups).
