I have this chemistry project where i have to design the square in the periodic table of elements for Rubidium (Rb). I cant name what it is on the square, but have to give clues with the design of the square. I've done research and found that it is silvery white liquid at room temperature. but i don't think I can work with much with this, especially if i dont put the name on it!! Can someone tell me a defining property or key feature of this element that I can incorporate into the design???

Rb is one of the elements that explodes when it comes into contact with water. That's definitely something to mention. And it's one of the few elements that is liquid at room temp. That's important too.
wikipedia says that Rb compounds are used in fireworks to make them purple.
And if you have a star trek junkie in your class, this might help:
Rubidium crystals are a key component of the subdermal transponders injected into Capt. James T. Kirk and Cmdr. Spock before they beam down to the surface of Ekos in the Star Trek episode "Patterns of Force".

Rubidium is the second most electropositive of the stable alkaline elements and liquefies at high ambient temperature (102.7°F = 39.3°C). Like other group 1 elements this metal reacts violently in water. In common with potassium and caesium this reaction is usually vigorous enough to ignite the liberated hydrogen. Rubidium has also been reported to ignite spontaneously in air. Also like other alkali metals, it forms amalgams with mercury and it can form alloys with gold, caesium, sodium, and potassium. The element gives a reddish-violet color to a flame, hence its name....
