Welcome to the chapter "Classification of Elements & Periodicity in Properties". This chapter introduces you to Periodic Tables and Classification of Elements.  It starts with walking you through the Genesis of Periodic Classification and walks you through how the periodic tables have evolved to the current modern periodic tables. This chapter covers some very important concepts which sets the tone for the rest of the Chemistry chapters. Hence this chapter is very important for ones understanding. 

The topics covered in this chapter include  

  • Genesis of Periodic Classification
  • Earlier Periodic Tables
  • Modern Periodic Law and the Present Form of the Periodic Table
  • Electronic Configurations and Periodic Table
  • Long-Form of Periodic Table
  • Screening Effect - Effective Nuclear Charge
  • Periodic Trends in Properties of Elements
  • Atomic Radius
  • Ionization Energy
  • Electron Affinity or Electron Gain Enthalpy
  • Electro negativity

The videos included in this chapter contain lots of animations, illustrations, pictures, analogies etc., which explains the basic concepts as well as complex topics of Chemistry in a lucid manner.

The quizzes tests included in this Chapter are a blend of Basic level, Intermediate level and Advanced level Multiple Choice Questions(MCQ), designed exclusively for NEET aspirants. The main objective of the videos and incorporated MCQs is to facilitate students to crack NEET Exam with 100% success rate.
