Malleability

high

Malleability is the property of a metal by which it can be beaten or rolled into thin sheets without breaking.

If the object is made into a sheet, think malleability first.

Ductility

high

Ductility is the property of a metal by which it can be drawn into wires without breaking.

If the question says wire, choose ductility.

Sonorous

high

Sonorous is the property of a metal by which it produces a ringing sound when struck.

If the object rings when struck, think sonorous.

Reactivity Series

high

The reactivity series is the arrangement of metals in decreasing order of their reactivity.

Always compare the position of two metals before predicting displacement.

Ionic Compound

high

An ionic compound is a compound formed by attraction between oppositely charged ions.

Check the state first: solid ionic compound usually does not conduct, but molten or aqueous ionic compound can conduct.

Rusting Prevention

high

Rusting prevention means stopping iron from coming into contact with both air and moisture.

In every rusting answer, mention both air and moisture clearly.

Amphoteric Oxide

high

An amphoteric oxide is an oxide that reacts with both acids and bases.

If an oxide reacts with both acid and base, amphoteric is the correct idea.

Electrolytic Refining

high

Electrolytic refining is the method of obtaining a pure metal by using electricity in an electrolytic cell.

Remember: impure metal at anode, pure metal at cathode, anode mud at the bottom.

Alloy

medium

An alloy is a homogeneous mixture of two or more metals, or a metal and a non-metal, made to improve useful properties.

In exams, mention that alloys are mixtures made to improve properties.

Non-Metal Oxides

medium

Non-metal oxides are usually acidic oxides formed when non-metals combine with oxygen.

If a non-metal oxide reacts with base or forms acid in water, think acidic oxide.
