Ice

At earth's atmospheric pressure 

Hydrogen freezes solid at -259.16 °c.
Oxygen freezes solid at -218.79 °c.
Nitrogen freezes solid at -210 °c 
Carbon Dioxide freezes solid at  -78.5 °c  

Helium won't freeze at any temperature in Earth's atmospheric pressure except absolute zero which is impossible. 

If you made a bowl out of frozen carbon dioxide, Helium, Hydrogen, Oxygen, and Nitrogen ice would boil in it. 

Oxygen ice is magnetic as is liquid oxygen.
