During a chemical reaction, an iron atom became the ion fe2+. what happened to the iron atom?

The Iron atom lost two electrons to become the Fe2+ ion. This is referred to as oxidation.

            The Iron atom got oxidized.

Explanation:

                        In inorganic chemistry Oxidation and Reduction reactions are defined as,

Reduction:

                 The reaction in which an atom accepts electrons is known as reduction reaction.

Example:

                                      2 Na  +  Cl₂    →     2 NaCl

In this reaction Chlorine oxidation state has changed from 0 to -1. Hence, it has gained one electrons therefore, it is designated as being reduced.

Oxidation:

                 The reaction in which an atom looses electrons is known as reduction reaction.

Examples:

                                      2 Na  +  Cl₂    →     2 NaCl

In this reaction Sodium's oxidation state has changed from 0 to +1. Hence, it has lost one electrons therefore, it is designated as being Oxidized.

                                       2 Fe + 3 O₂    →     2 FeO

In this reaction Iron's oxidation state has changed from 0 to +2. Hence, it has lost two electrons therefore, it is designated as being Oxidized.

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
