What is the electron configuration of Sc+3?

Answer 1

Mateo Aguilar

You got scandium...#Z=21#, i.e. 18 electrons to distribute in the trication.

And so we follow the usual #"Aufbau scheme"#...

#underbrace(1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^1)_"electronic configuration of scandium metal"#

#underbrace(1s^(2)2s^(2)2p^(6)3s^(2)3p^(6))_"electronic configuration of scandium trication"#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
