About Palladium
Palladium is a chemical element with the symbol Pd and atomic number 46, meaning every atom has 46 protons in its nucleus. It is classed as Transition metal and is a solid at room temperature. Its atomic mass is about 106.42 atomic mass units (u).
On the periodic table, Palladium sits in group 10, period 5, which determines how many electron shells it has and how it tends to react with other elements.
Uses of Palladium
In daily life and industry, Palladium is used for Catalysts, jewellery. These uses are closely tied to the typical properties of elements in the Transition metal category.
Electron Structure of Palladium
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), Palladium has 4 electron shells, with an approximate arrangement of 2, 8, 18, 18 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.
