In the early 19th century, chemists were in a quest to unravel the mysteries of the periodic table. They were intrigued by the existence of a gap between calcium and titanium, an empty spot waiting to be filled by an unknown element. This uncharted territory fueled their curiosity and motivated them to explore further.

It was in 1879 when a Swedish chemist named Lars Fredrik Nilson was conducting experiments on a rare mineral called euxenite. He managed to isolate a new element from this mineral and named it scandium, after Scandinavia, the region where it was discovered.

The electronic configuration of scandium is 1s2 2s2 2p6 3s2 3p6 4s2 3d1. This configuration highlights the arrangement of electrons within scandium’s atomic structure, indicating the number of electrons present in each energy level or orbital.

Scandium has 21 electrons, distributed among its various energy levels. The first two electrons occupy the 1s orbital, followed by two electrons in the 2s orbital and six in the 2p orbital. The next eight electrons fill the 3s and 3p orbitals.

Interestingly, scandium’s electronic configuration deviates from the pattern observed in its neighboring elements. While it belongs to Group 3 of the periodic table, scandium possesses an electron configuration similar to that of the transition metals in Group 4. This peculiarity adds to its uniqueness and sets it apart from other elements.
