ngenium

Ngenium is a hypothetical element with the atomic number 120. As of its theoretical conception, it has not been synthesized or observed, and therefore its properties are largely unknown and subject to prediction based on periodic trends. Elements with atomic numbers greater than 103 are considered transuranic and are typically highly unstable, decaying rapidly.

Based on its position in the periodic table, ngenium would likely fall into group 2, making it an alkaline earth metal. This would suggest that it would share some chemical similarities with other elements in this group, such as calcium and strontium. It is predicted to be a solid at room temperature, though this is highly speculative. The electron configuration is expected to be [Og] 8s^2, placing it in the eighth period.

The name "ngenium" is a placeholder, following IUPAC's systematic element naming convention for undiscovered elements. The provisional symbol would be Ubn. Research into superheavy elements like ngenium is part of ongoing efforts in nuclear physics and chemistry to explore the limits of the periodic table and understand the fundamental forces that govern atomic nuclei. The synthesis of such elements is extremely challenging, requiring specialized particle accelerators and sophisticated detection methods.
