Worked practice questions

Which element of group 1 is NOT counted among the alkali metals?

  1. Hydrogen
  2. Caesium
  3. Lithium
  4. Sodium
Show answer and solution

Correct answer: A. Hydrogen

Hydrogen sits in group 1 but is a non-metal under ordinary conditions, so only the other members are called alkali metals.

Why does francium not occur appreciably in nature?

  1. It forms insoluble oxides in rocks
  2. It is consumed by marine organisms
  3. It is radioactive with a short half-life
  4. It is lost as a volatile vapour
Show answer and solution

Correct answer: C. It is radioactive with a short half-life

Francium decays quickly because its half-life is very short, so it never accumulates.
