About Tennessine
Tennessine is a chemical element with the symbol Ts and atomic number 117, meaning every atom has 117 protons in its nucleus. It is classed as Unknown and is a solid at room temperature (estimated, never measured directly because this element decays within seconds). Its atomic mass is about 294 atomic mass units (u).
On the periodic table, Tennessine sits in group 17, period 7, which determines how many electron shells it has and how it tends to react with other elements.
Uses of Tennessine
In daily life and industry, Tennessine is used for Research. These uses are closely tied to the typical properties of elements in the Unknown category.
Electron Structure of Tennessine
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), Tennessine has 7 electron shells, with an approximate arrangement of 2, 8, 18, 32, 32, 18, 7 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.
