I. When iron reacts with oxygen an iron oxide compound with the formula of \( F e_{2} O_{3} \) can be formed II. Iron atoms form cations with a charge of +3 by losing 3 electrons and oxygen atoms gain 2 electrons to form an anion with a -2 charge.

  1. Statement \( I \) is true, Statement \( I I \) is true and is a correct explanation of the phenomena described in 1
  2. Statement I is true, Statement II is false
  3. Statement I is false, statement II is true
  4. Statement I is false, Statement II is false

Correct answer: Statement I is true, Statement II is false

Solution

Fe2O3 is a real iron oxide, so Statement I is true. Statement II is false because oxygen does gain 2 electrons to become O2−, but the statement about iron is not generally correct as written for this compound’s formation context.
