Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 35-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

How the two modes differ
No account needed

Normal

Untimed

Every question on one page, loading as you scroll. Choose an option and see straight away whether it was right.

  • No timer. Nothing to start and nothing to submit. Stop whenever you like.
  • Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
  • Solutions in place. The explanation, and the video where one has been added, sit under the question.
  • Open to guests. Normal practice needs no sign-in.
Real exam conditions

Simulated

Timed CBT

The computer-based test format: one clock, a question palette, and a score the moment you submit.

  • A clock that does not pause. 35 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
  • Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
  • Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
  • Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.

About this test

Metals and Non-Metals GK Practice Quiz Level 3: Reactivity, Alloys and Extraction

This Level 3 Metals and Non-Metals GK quiz on Aptitude360 tests general science chemistry through statement-based, match-the-list and ordering questions. It covers the reactivity series, alloy composition, metallurgical processes, corrosion and the exceptions that break the usual rules. Every question comes with a written explanation.

Topics covered in this Metals and Non-Metals set

  • Ordering metals such as potassium, sodium, calcium, aluminium, zinc, iron, lead, copper, mercury, silver and gold by reactivity
  • Composition of brass, bronze, solder, steel and amalgam
  • Roasting, calcination and the thermit reaction
  • Prevention of corrosion: galvanisation, tin plating, chrome plating, painting and alloying
  • Acidic, basic and amphoteric oxides
  • Exceptions such as mercury, caesium, lithium, iodine, diamond and graphite
  • Carat system for gold and the rust-free Iron Pillar in Delhi

Key concepts to revise for metals and non-metals GK

  • Physical properties: malleability, ductility, lustre and conduction of heat and electricity
  • Position of metals above and below hydrogen in the reactivity series
  • Why less reactive metals like gold and silver occur in the free state
  • Uses linked to properties, such as solder for joining wires and the thermit reaction for railway tracks

Revision tips for this chemistry GK topic

  • Learn the reactivity series with a mnemonic and practise placing mixed groups of metals in both increasing and decreasing order
  • Make a table of alloys with their constituent metals, since brass, bronze and solder are often confused
  • Keep a separate list of exceptions, such as liquid mercury, lustrous iodine and conducting graphite, because statement questions test them

Who should take this Level 3 quiz

Aspirants revising general science for competitive exams who are comfortable with the basics of metals and non-metals and want to test fine details with statement and matching questions.

FAQs about Metals and Non-Metals – GK Quiz with Answers – Level 3

What is the difference between metals and non-metals?
Metals are generally lustrous, malleable, ductile and good conductors of heat and electricity, and their oxides are generally basic. Non-metals are generally dull, brittle and poor conductors, and their oxides are generally acidic.
Which metal is liquid at room temperature?
Mercury is the metal that is liquid at room temperature. Caesium has such a low melting point that it can melt on the palm of the hand.
Which non-metal conducts electricity?
Graphite, an allotrope of carbon, is the non-metal that conducts electricity. This is why it is used to make electrodes.
What is the composition of brass and bronze?
Brass is an alloy of copper and zinc, while bronze is an alloy of copper and tin. Solder is an alloy of lead and tin.
