2 Iron atoms sulfur atoms oxygen atoms
Fe2 (SO4)3

10. Iron (III) and Sulfate ions
Describe one rule you used to decide on the correct, balanced formula for this compound
Make a neutral compound
Cation written first
Use parenthesis if more than one of each polyatomic ion used

11. Explain why anions are negative even though they are gaining electrons?
Since electrons are negatively charged, gaining an electron will give an atom more (-) charges than (+) charges from protons in the nucleus…thus the atom will become a negatively charged ion.
