The PDF consists of 8 pages covering the chapter “Periodic Classification and Properties” from Inorganic Chemistry. The topics are presented in a crisp and concise manner to aid in revision and memorization.

Topics covered are:

• Attempts at Classification of Elements. (All, from that of Lavoisier to the Modern Classification.)

• Periodic Properties: Atomic Radius/Size, Ionization Enthalpy/Potential, Electron Affinity/Electron Gain Enthalpy, Electronegativity.

• Other Points: Inert Pair Effect, Valency with respect to Hydrogen.

Remember that, while this material can help you grasp concepts, full-fledged notes should be refered to fully understand them.
