What is the orbital notaion and the room temp. for iron??

Answer 1

^The answer above is correct^
To simplify, the notation is 1s2 2s2 2p6 3s2 3p6 4s2 3d6

Perhaps you mean Iron's state at room temperature? Well, it's a solid...

Answer 2

I don't get the room temperature connection.
If I remember right, Fe is atomic number 26
So we can fill orbitals:
1s2 Left to fill 24
2s2 2p6 Left to fill 16
3s2 3p6 Left to fill 8
4s2 Left to fill 6
We reach the first group of transition metals where the next electrons fill an inner shell
3d6 Left to fill =0
