8. Sirium

Symbol: Sr

Atomic Number: 119

Atomic Mass: 315

Ion: Sr118+

Melting Point: 30°C 

Boiling Point: 630°C

Half-life: Surprisingly high, approximate value unknown as of yet.

Behaviour and Reactivity: Similar to those of potassium.

Conductivity of Electricity and Heat: High

Density: 3g/cm3

Appearance: Mauve brittle alkali metal. Has no isotopes that are known.

Origins: In an presumably haunted mansion in a range of mountains. It was found in a discreet area underneath a guest room. However, it is only a small portion (a couple grams) and was bought by NASA.

Costs: $50,000,000/gram (twice as expensive as californium, the then most expensive element). This is because it contains a hundred million MJ of energy per gram (approcimately twelve million more MJ than dueterium, the then fuel with the highest energy density).

Interesting Fact: Shortly after the owner of the mansion found the element, he found four strangers trapped inside his mansion and the main door mysteriously locked. Apparently, after some questioning, one of them revealed that they had arrived (not as a group) to find a material  which presumably grants a wish. However that turned out to be a result of specious rumours and the material was this element. He threw them all out of a nearby window (fortunately nobody was injured) and sold the material to NASA, who were somehow informed of the location and existence of this material. Originally going to be named Ununennium, but due to the owner's protests (and some say offering of money) the element was named after the avaricious sociopath.
