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 25-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. 25 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

Periodic Table GK Quiz Level 1: Basics of Classification and Trends

Beginners in General Awareness chemistry can start here: this Level 1 Periodic Table GK quiz covers how elements were first classified and how the modern table is arranged. Questions span Döbereiner, Newlands, Mendeleev and Moseley, then periods, groups and simple trends. Aptitude360 gives an explanation with every answer.

What this beginner periodic table quiz covers

  • Döbereiner's triads and Newlands' Law of Octaves, including its musical comparison
  • Mendeleev's table based on atomic mass and chemical properties, with gaps for undiscovered elements
  • Eka-boron, Eka-aluminium and Eka-silicon, and the Sanskrit origin of the prefix
  • Moseley's atomic number and the Modern Periodic Law
  • Periods, groups and the placement of metals, non-metals and metalloids
  • Change in atomic size and metallic character across a period and down a group

Key concepts every beginner should know

  • Horizontal rows are periods and vertical columns are groups
  • Elements in a group show similar chemical properties
  • Atomic size falls across a period and rises down a group
  • Metalloids such as boron, silicon and germanium are also called semi-metals

Revision tips for periodic table basics

  • Learn each predicted Eka element alongside the real element it became
  • Remember trends in pairs: atomic size and metallic character move the same way

Who this Level 1 quiz is for

It is meant for General Awareness aspirants at the start of their chemistry preparation, before moving on to the higher levels.

FAQs about Periodic Table – GK Quiz with Answers – Level 1

How many groups and periods are there in the modern periodic table?
The modern periodic table has eighteen vertical groups and seven horizontal periods.
Who is known as the father of the periodic table?
Dmitri Mendeleev, a Russian chemist, is given the main credit for the periodic table. He arranged elements by atomic mass and chemical properties and left gaps for undiscovered elements.
What is the Modern Periodic Law?
The Modern Periodic Law states that the properties of elements are a periodic function of their atomic numbers. It follows from Henry Moseley's work in 1913.
What are metalloids in the periodic table?
Metalloids are elements with properties between metals and non-metals, such as boron, silicon, germanium and arsenic. They lie along the zig-zag border separating metals from non-metals.
