Scandium/Atomic number
Why are Sc 3 ions white in color?
There is one d electron present in the 3d subshell. When light falls on the Ti3+ complex, the t2g electron is excited to the eg level. There are no d electrons; hence, d–d transition is not possible. Hence, Sc3+ is colourless.
Is Sc 3 a cation or anion?
Answer and Explanation: The electronic configuration of scandium is [Ar]3d14s2 [ A r ] 3 d 1 4 s 2 . Scandium can easily lose three electrons to attain a stable noble gas configuration. Hence scandium is most likely to form a cation which can be noted as Sc3+ S c 3 + .
How do you find the electric charge?
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.
What is scandium (Sc)?
Scandium is an element with the atomic number 21 and represented with the symbol ‘Sc‘ in the periodic table. Scandium is mined from one of the rare minerals from Scandinavia. The colour it develops when exposed to air is yellowish or pinkish cast. One of the characteristics of Scandium is it gets tarnished and burned easily if ignited.
What is the most common charge on an element?

What is the charge on an atom related to?
The charge on an atom is related to its valence electrons or oxidation state. An atom of an element is most stable when its outer electron shell is completely filled or half-filled.
