Hi everyone.
00:01
In this question, using the short hand notation create box diagrams for the electronic configuration of iron atom, then iron 2 plus ion and iron 3 plus ion.
00:14
And find out which is more stable.
00:17
So here, atomic number of iron, that is 26.
00:20
So the electronic configuration of iron, that is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2 and 3d6.
00:28
So this electronic configuration of iron, that is 1s2, 2s2, 3s2 and 3d6.
00:28
So this electronic configuration, we can find.
00:30
Filled with the help of opposite principle so according to this principle the electrons are filled up in increasing order of the energy in the sub -shed so this electronic configuration we can also return as argon because argon having 18 electron then 4s 2 3d6 now in case of iron we have the electronic configuration that is argon 4 s 2 3d6 now we have to fill 2 electron in 4 s and 3d6 that means 6 in 3d subshell.
01:02
So 1, 2, 3, 4, 5, 6, like this.
01:06
Now, this filling can be on the basis of the hounstrol of maximum multiplicity, which states that electrons are distributed among the orbital of subshell in such a way as to keep maximum number of unpaid electrons with parallel spin.
01:21
Then we have iron 2 plus ion.
01:24
So we have to remove 2 electron so that the 2 electrons will remove from 4s orbital so we have argon for a zero 3d6 that mean we have to fill only these six electrons in 3d suction so one two three four five six now coming to the this iron three plus ion so here two electrons are removed so here we have to remove for two electrons from fours and one electron from 3d because we have to remove total three electrons so two electrons from 4s and one electron from 3d orbital...
