عن Oganesson
Oganesson is the heaviest element on the periodic table. Despite being a noble gas by group, it may be a solid at room temperature and may not have a closed electron shell. Only five or six atoms have ever been produced.
Uses & Applications
No practical applications. Scientific research only.
حقيقة مضحكة
Oganesson may be solid at room temperature and could form chemical bonds, completely defying noble gas conventions.
