V3+ Electron Configuration

Why V3 + ion has electron configuration [Ar] 3d2 instead of [Ar] 4s2? 3

What is the electron configuration of Mn3 + ion?

update

Mark, in answer to your question, what is the highest energy level, what kind of ■■■■ electrons will you lose while making cation, this is the root of my question! If the 3d energy level is higher than the 4s level, then why does the V3 + ion lose electrons with less energy than the first 4s level ???????????

Due to D-electron protection, 4s electrons are less strongly attached to the nucleus. Therefore, the first electron to be lost is the 4s electron which makes V3 +. However, the most stable oxidation state of V is +5.

That's why the Mn3 + configuration is [Ar] 3d4.

V3+ Electron Configuration

The first one is correct, the outer S electrons are less strongly connected to the nucleus, they are carried first. (For information V = 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 3)
So yes, first remove the 4s2 electron and get V2 + (1s 2 2s 2 2p 6 3s 2 3p 6 3d 3)
Again you have to take another step to get to V3 + and then lose the valence electron at the end of s (3d), which makes 1s 2 2s 2 2p 6 3s 2 3p 6 3d. Convert EC 2 or [Ar] 2d 2 in VEC format.

For women,
Your question relates to the basic electronics configuration of VIII ions.
As you know, VM is a transfer metal and can partially change the quality of your electronic mouth. In addition, spells and portals as well as individual electrons are evaluated. What is the highest energy level in this type of electronic ■■■■, ie what type of electronic ■■■■ will be lost during the formation of cations? Different chemical elements have s electrons as valence electrons, so I would guess that p loses more electrons, followed by s electrons.
Thus, the wave loses 3 electrons which form a small cation: these electrons are joined by a third ■■■■ electron (two electrons) and a third electron (third electron).
ut manganese (III) We can write:
[Air] 3W4.
I can help you.
I wish you a good ht.
