Periodic Properties and variations of Properties – Physical and Chemical. [PART - 3]

THE SCOPE OF SYLLABUS:

(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 3 (students to be exposed to the
complete modern periodic table but no
questions will be asked on elements
beyond period 3 – Argon);
• 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).
