Question

The number of 3d electrons in fe3+ ions is equal to

Answer 1

$\huge\mathbb{\blue{QUESTION-}}$

The number of 3d electrons in fe3+ ions is equal to.

$\huge\mathbb{\blue {SOLUTION}}$

Electronic Configuration of Fe is ⎯

${\sf [Ar]\:4s^2\:3d^6 }$

After lossing 3 electrons $\sf{Fe^{+3}}$

It's configuration changes to ⎯

${\bf \red{ [Ar]\:3d^5}}$

$\huge\mathbb{\blue {ANSWER-}}$

So , number of 3d electrons in ${\sf Fe^{+3}}$ ions is equal to ${\bf \red{5}}$

Answer 2

Answer:

NUMBER OF 3D ELECTRONS IN fe³+ ions is 5
