Chattogram Board 2022

From left to right in the periodic table:

  1. i. metallic property decreases
  2. ii. ionization energy increases
  3. iii. atomic radius increases

Think it through first, then pick an option.

  1. a i and ii
  2. b ii and iii
  3. c i and iii
  4. d i, ii and iii
Answer and explanation

Correct answer: a i and ii

i and ii both hold: metallic property falls to the right; smaller radius raises ionization energy.

Why the other options are wrong

  • b ii and iii: iii does not hold: size falls along a period. The answer is i and ii.
  • c i and iii: iii does not hold: size falls along a period. The answer is i and ii.
  • d i, ii and iii: iii does not hold: size falls along a period. The answer is i and ii.
