How scandium, a transition metal forms an ion near a aristocrat gas structure?
Sc, scandium, can drop 3 electrons to have the same electron configuration as Argon (Ar). Sc within its normal state has 3 electrons contained by its 4th shell. By dropping those 3, it can be “happy” with a full valence electron shell. Therefore, it becomes Sc 3+. . . .

How scandium, a transition metal forms an ion near a member of the aristocracy gas structure?
Do you mean electronic configuration? Scandium will have titled gas configuration by losing 3 outer electrons: its p electron and both s electrons. Then it will have the same electronic configuration as Argon, because it will hold the same number of electrons on the. . .
