New element discovered!

Archer has been enjoying his SLUFY "World of Matter" class. They've talked about elements, atoms, and the periodic table. Earlier this week, each student created a new element; Archer's was called Slufium, an element he told me was used to make periodic tables and sunscreen. Here's the description he wrote in his press release:

Atomic number: 10
Symbol: Sf
Atomic weight: 18.6608909986333...

Boiling point (Celsius): -359
Melting point (Celsius): -459
State of matter at room temperature: Solid

Chemical and physical properties: Slufium is very cold, boiling point colder than Antarctica. Metallic, used for periodic tables, colder than 0 Kelvin.

What are the potential uses for your element? It is use-ful for sunscreen, SPF 5000, makes you especially protected from the sun.
