Periodic Table and Inorganic Chemistry MCQs from the NAT-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · COMSATS Past Paper 07 · Periodic Table and Inorganic Chemistry
The most electronegative element in the periodic table is:
- A.oxygen
- B.fluorine
- C.chlorine
- D.nitrogen
Show answer
Answer: B. fluorine — Fluorine (3.98 on the Pauling scale) is the most electronegative element.
- Q2 · COMSATS Past Paper 06 · Periodic Table and Inorganic Chemistry
In the Haber process for making ammonia, iron is used as:
- A.a product
- B.a reactant
- C.a catalyst
- D.an inhibitor
Show answer
Answer: C. a catalyst — Iron speeds up N₂ + 3H₂ ⇌ 2NH₃ without being used up.
- Q3 · COMSATS Past Paper 05 · Periodic Table and Inorganic Chemistry
Down a group of the periodic table, the first ionisation energy generally:
- A.stays the same
- B.doubles with each period
- C.increases
- D.decreases
Show answer
Answer: D. decreases — Outer electrons are further from the nucleus and more shielded, so they are easier to remove.
