Final answer:
An iron ion with 56 protons and a net charge of +5 would require 51 electrons to balance the net positive charge, due to the loss of 5 electrons.
Step-by-step explanation:
The question is asking about the electronic configuration of an iron ion with a net charge of +5e. Iron (Fe) inherently has 26 protons, and the neutral atom would also have 26 electrons. However, if the ion of iron has a net charge of +5, this means it has lost 5 electrons. Therefore, the total number of electrons in this iron ion would be the number of protons (which defines the element) minus the net charge due to the loss of electrons.
Since the iron ion has 56 protons (which is a mistake as natural iron has 26 protons, but we'll follow the given information), the number of electrons it would need to have to result in a +5 charge would be:
56 protons - 5 net charge = 51 electrons.
