CONTENTS

Chemistry of inner-transition metals: Lanthanides series – general characteristics of

lanthanides. Extraction of a mixture of lanthanides from monazite sand, separation of lanthanides

by – fractional crystallization and precipitation, solvent extraction, change of oxidation states,

ion exchange chromatography and complex formation methods. Uses of lanthanides. Lanthanum

compounds – lanthanum oxide, halids, chloride, bromide, iodide, sulphate, nitrate and carbonate.

Actinide series – Introduction, electronic configuration, sources of actinides, properties of

actinides – oxidation states, ionic radii, colour, formation of actinides compounds. Comparison

of actinides with lanthanides. Magnetic properties of lanthanides and actinides. Absorption

spectra of lanthanides and actinides.

Trans-uranium elements, further extension of periodic table, super heavy elements (SHE). f – BLOCK ELEMENTS FOR for Class 11th, 12th, BSc & MSc
