In a chemical reaction, an iron atom became the ion fe2+. what happened to the iron atom?
a. it lost electrons and was oxidized.
b. it lost electrons and was reduced.
c. it gained electrons and was oxidized.
d. it gained electrons and was reduced.

 The correct option is (A).

Explanation:

Oxidation Is a reaction in which loss of an electrons from an atom is involved in a reaction is known as oxidation.

Reduction Is a reaction in which gain of an electrons by an atom is involved in a reaction is known as reduction.

In a chemical reaction, an iron atom became the ion which means that iron atom by loosing two electrons from its valence shell has oxidized into positively charged ion.

So, the correct option (.A)

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
