Caesium

Francium
YES
NO
Francium and Caesium can become liquid at or just above standard room tempurature
A nice idea but there are several problems. Firstly, the time limit - I never even reached question 10. Secondly that question has errors. For one thing you ought to state "room temperature and pressure" (RTP), since practically anything which is gaseous at RTP can be liquefied by increasing the pressure. Secondly, it is debatable whether Caesium is a liquid at room temperature - it melts at 28.5 degrees, which is above the temperature in my room! Francium likewise as it probably has a melting point of about 27. Also, iron is pretty common in the body - in every red blood cell. Also, arguably, zinc. More controversially, in my book Cd and Hg are transition metals.
