About Copernicium
Copernicium is a chemical element with the symbol Cn and atomic number 112, meaning every atom has 112 protons in its nucleus. It is classed as Transition metal and is a solid at room temperature (estimated, never measured directly because this element decays within seconds). Its atomic mass is about 285 atomic mass units (u).
On the periodic table, Copernicium sits in group 12, period 7, which determines how many electron shells it has and how it tends to react with other elements.
Uses of Copernicium
In daily life and industry, Copernicium is used for Research. These uses are closely tied to the typical properties of elements in the Transition metal category.
Electron Structure of Copernicium
Using a simplified electron shell model (at most 2 electrons in the first shell, 8 in the second, 18 in the third, and so on), Copernicium has 7 electron shells, with an approximate arrangement of 2, 8, 18, 32, 32, 18, 2 electrons from the innermost shell to the outermost. This is a simplified learning model, not the full electron configuration that accounts for the s, p, d and f subshells.
