Question

an individual cation from the iron (iii) oxide compound would contain __ protons and __ electrons. answer:

Explanation:

Step1: Find Fe's proton count

Iron (Fe) has an atomic number of 26, so protons = 26.

Step2: Determine cation charge

Iron(III) means a +3 charge, so electrons = protons - 3.
<Expression>
$26 - 3 = 23$
</Expression>

Answer:

26 protons and 23 electrons
