Ru2+ Electron Configuration

Electronic configuration for Ru2 +? 3

The computer writes the order of the electrons in the form of Co, for example [Ar] 3d (7) 4s (2), which we will write [Ar] 3d74s2.

In the computer format below, enter the electronic configuration of the ion.

Note: Write the electronic configuration shown in Table IC before your text. That is, insert 4f into 5d.

Ru2 +

Ru2 + = 1s (2) 2s (2) 2p (6) 3s (2) 3p (6) 4s (2) 3d (10) 4p (6) 5s (2) 4d (4)

= [Air] 3d (10) 4s (2) 4p (6) 4d (4) 5s (2)

As you should say, in the ic row it will look like this:

= [Air] 4s (2) 3d (10) 4p (6) 5s (2) 4d (4)

When you get stuck, you can use the following sketch to help yourself:

1 second

2s 2p

3s 3p 3d

4s 4p 4d 4f

5s 5p 5d 5f

The sequence of ss is found by drawing a diagonal line through each set, for example 1s from right to left, then 1s for 2s, then 1p for 2p and 3s, and so on.

Really ...

Ru's ground condition is irregular. Instead of being [Kr] 5s 2 4d 6 as you think, it's actually [Kr] 5s 1 4d 7

And then when you add the charge, you remove the electrons from the n submarine, that is, 5. You take one of the two electrons and the submarine is empty, so you go to 4d to get the other electron. (Because you are not drowning in nuclear electrons)

Your answer is:

Ru2 + = [Kr] 4d 6
