Answer:
C. 1 proton 3 neutrons
Explanation:
A nucleus is more stable if the ratio of the neutrons to protons is between 1:1 and 1:1.5.
Thus the ratios of neutrons to protons for the nuclei are as follows
A- 1:1
B- 1:1
C- 1:3
D- 1:2
Among these ratios, C is the greatest thus the nucleus is the least stable.
Fe (III) is just Fe^+3.
Oxide is O^-2
When you write them into a chemical formula, they all need to have a neutral charge. You will need two Fe^+3 and three O^-2.
This gives you Fe2O3.
