Chemistry

1. ATOMIC STRUCTURE:

Electromagnetic Radiation: Wave nature - Wave Characteristics: Wave length - frequency - Wave number - units to express these quantities - relationship between them.

Atomic Spectrum of Hydrogen - different regions of the spectrum - wave number of the spectral lines in these regions (Rydberg's equation),. Lyman, Balmer , Paschen , Bracket and Pfund series.

Atomic Models : Rutherford's model, merits and demerits

Bohr's Model: Postulates - formulation of the model - Expressions for the energy and radius of the Hydrogen Atomic orbits with derivations - limitations. Zeemen, Stark effects - Sommerfields modifications.

Quantum Numbers: Significance - writing quantum numbers for differentiating electrons in atoms - Pauli's exclusion principle.

Wave nature of electron: De-Broglie wave equation - Heisenberg's uncertainty principle , Schroedinger's equation (Cartesian coordinates equation only).

Orbitals: Shapes of s,p,d orbitals - orbitals energy sequence - aufbau principle - Hund's rule. Electronic configuration of elements (from atomic no: 1 to 30 by nlx method)

Stability and magnetic behaviour of atoms based on concepts of electronic configuration.

II. NUCLEAR CHEMISTRY:

Nuclear particles: (Protons, Neutrons) - isotopes, isobars, isotones and Isodiapheres.

Nucleus: Relative dimensions of atom and nucleus - nuclear mass defect - mass -energy relation - binding energy - n/p ratio - magic numbers.

Nuclear reactions: Writing nuclear reactions in the shortest form of (M(a,b)M') notation, balancing - typical examples of nuclear reactions - nuclear fusion (proton) reactions - nuclear fission (uranium - 235) - Differences between nuclear and Chemical reactions.

Radioactivity: Units of radioactivity (Curie, Rutherford and Bacquerel) - natural and artificial radioactivity - disintegration series - Group displacement law.

Radioactive disintegration: Rate equation (no derivation) - decay constant - half-life period - numerical problems on radioactive disintegrations - Radioactive isotopes (O18, P32, U238, C14, I131)and their applications
