Worked practice questions
Which group has elements in all three main states at STP?
- Group 1
- Group 15
- Group 18
- Group 17
Show answer and solution
Correct answer: D. Group 17
Group 17 has gases (F2, Cl2), a liquid (Br2) and a solid (I2) at standard conditions.
Astatine is usually produced by alpha bombardment of
- Lead
- Bismuth
- Polonium
- Thallium
Show answer and solution
Correct answer: B. Bismuth
Bombarding bismuth with alpha particles adds two protons, giving element 85, astatine.
