Question

In iron atom ,how many electrons atom have n=3 & l=2?

Answer 1

Heya user !!!

Here's the answer you are looking for

Iron (Fe) has atomic number 26

And n=3 means the shell number is 3

and l = 2 means the subshell is d

So the question says how many electrons are there in 3d orbital

The electronic configuration of Fe goes this way
1s² 2s² 2p6 3s² 3p6 4s² 3d6

So here, 6 electrons are there in 3d.

Answer 2

n=3 means 3rd shell...

and l=2;means. d orbital..
so ,in iron element ..
in 3d orbital. ..number of electrons is 6.
as outer electronic configuration of iron element is 3d6 4s²
