Question

Which element becomes a cation?
*
oxygen
sulfur
aluminum
nitrogen
Not Sure

Answer 1

Among the elements listed, aluminum becomes a cation. Aluminum typically loses three electrons to achieve a stable electron configuration, forming the Al³⁺ cation.

In contrast:
- Oxygen and sulfur tend to gain electrons to form anions (O²⁻ and S²⁻, respectively).
- Nitrogen also tends to gain electrons to form an anion (N³⁻).

So, the correct answer is aluminum.
