Worked practice questions

Within a period, where does an alkali metal rank in first ionisation energy?

  1. Close to the halogens
  2. A middle value
  3. The highest value
  4. The lowest value
Show answer and solution

Correct answer: D. The lowest value

The single outer electron is far from the nucleus and shielded, so it is easy to remove.

How do alkali metal hydroxides rank in basic strength?

  1. Strongly acidic in water
  2. Most basic of all hydroxides
  3. Amphoteric in nature
  4. Only weakly basic in water
Show answer and solution

Correct answer: B. Most basic of all hydroxides

Group 1 hydroxides ionise completely and are the strongest hydroxide bases.

Aluminium oxide reacts with alkali hydroxides to give which salts?

  1. Aluminate salts
  2. Aluminide salts
  3. Double alum salts
  4. Hydrated aluminium
Show answer and solution

Correct answer: A. Aluminate salts

Amphoteric oxides such as Al2O3 dissolve in strong alkali forming aluminates.
