What is the Ionic Charge of Scandium (Sc)? And Why?

The Ionic Charge of Scandium (Sc) is 3+.

But the question is how can you find the ionic charge on Scandium (Sc)?

The ionic charge of scandium depends on what it is bonded with.

So let’s try to find out the ionic charge of Scandium (Sc) using some examples.

You can also refer to the below video from which you will learn to find charge of any ion.

How to find the ionic charge of Scandium (Sc)?

As I mentioned earlier, the ionic charge of Scandium (Sc) can be found out by looking at what it is bonded with.

So let’s take examples of compounds of Scandium (Sc) like ScCl₃, ScF₃, Sc₂O₃, etc.

Example 1: ScCl₃
In ScCl₃, the Scandium (Sc) is bonded to Chlorine (Cl).
You know that the ionic charge of Cl is 1-.
So you can easily say that the ionic charge of Sc should be 3+, then only it will get canceled out.
Hence the ionic charge of Scandium in ScCl₃ is 3+.

Example 2: ScF₃
In ScF₃, the Scandium (Sc) is bonded to Fluorine (F).
And again, you know that the ionic charge of F is 1-.
So here also you can easily say that the ionic charge of Sc should be 3+, then only it will get canceled out.
Hence the ionic charge of Scandium in ScF₃ is 3+.

Example 3: Sc₂O₃
Similarly in Sc₂O₃, the Scandium (Sc) is bonded to Oxygen (O).
And you know that the ionic charge of O is 2-.
So from this, you can easily say that the ionic charge of Sc should be 3+, then only it will get canceled out.
Hence the ionic charge of Scandium in Sc₂O₃ is 3+.

In this way, charge of Scandium depends on what it is bonded to.

As seen from the above examples,
The charge of Scandium (Sc) is 3+.

I hope you have understood why scandium has 3+ ionic charge.
