About Nickel
Nickel is a chemical element with the symbol Ni and atomic number 28, meaning every atom has 28 protons in its nucleus. It is classed as Transition metal and is a solid at room temperature. Its atomic mass is about 58.693 atomic mass units (u).
On the periodic table, Nickel sits in group 10, period 4, which determines how many electron shells it has and how it tends to react with other elements.
Uses of Nickel
In daily life and industry, Nickel is used for Stainless steel, EV batteries (Indonesia is a major producer). These uses are closely tied to the typical properties of elements in the Transition metal category.
Electron Structure of Nickel
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), Nickel has 3 electron shells, with an approximate arrangement of 2, 8, 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.
