বিষয়ে Copernicium
Copernicium may behave more like a noble gas than a metal due to strong relativistic effects. It was produced by fusing lead and zinc nuclei.
Uses & Applications
No practical applications. Scientific research only.
মজা কথা
Copernicium might be gaseous at room temperature due to relativistic effects, making it nothing like mercury, its lighter homolog.
