About Metals and Non-metals

This quiz covers Chapter 3 of CBSE Class 10 Chemistry, Metals and Non-metals.

It opens with the physical properties that distinguish metals from non-metals -- lustre, malleability, ductility, and conductivity -- along with well-known exceptions like mercury, sodium, iodine, and graphite.

It then covers the chemical properties of metals: how they react with oxygen, water, and dilute acids, and how this behaviour is organised into the reactivity series.

The quiz continues with how metals and non-metals actually combine to form ionic compounds, through the transfer of electrons, and the properties these compounds share.

It closes with how metals occur in nature as ores, how they are extracted based on their position in the reactivity series, how they are refined, and how alloys improve on the properties of pure metals.

Every question comes with a clear, simple explanation, so incorrect answers become as instructive as correct ones, whether you are revising for a school test or a board exam.
