Periodic Classification of Elements and Periodicity Quiz | MCQs

Periodic Classification of Elements and Periodicity is the name of the first chapter of FSc. Chemistry Part-II | 2nd Year. This post contains an online quiz | MCQs from chemistry chapter no.1 i.e. Periodic Classification of Elements and Periodicity.

All questions of this quiz are very important for the practice of final examinations, ECAT, MDCAT, and all entry tests for the universities of Pakistan and abroad.

We tried our best to choose | select maximum and important Multiple Choice Questions (MCQs) in this chapter.

This quiz is the version-1 of this chapter, the remaining questions of this Chapter No.1 (Periodic Classification of Elements and Periodicity) will be published soon.
