Attempt 4 A galvanic cell has an X electrode with X 2 plus ions in the left beaker and a Y electrode with Y 2 plus ions in the r
ight beaker. A salt bridge connects the two halves.A galvanic (voltaic) cell has the generic metals X and Y as electrodes. X is more reactive than Y, that is, X more readily reacts to form a cation than Y does. Classify the descriptions by whether they apply to the X or Y electrode.

Answer:
The electron configuration for Iron (Fe) with 26 electrons is as follows 1s²2s²2p⁶3s²3p⁶4s²3d⁶ (the superscripts add up to 26) or the Noble gas [Ar] 4s²3d⁶
Explanation:
The subshells fill up in the order 1s, 2s,2p, 3s,3p,4s,3d... (etc) the subshells have the following number of e⁻ (electrons) s: 2, p:6, d:10, f:14. I attached the subshell levels and where to find them on the periodic table that I made when I taught this to myself after lecture. You can use the noble gas from the previous row to make this simpler to write.
