What is the charge on the ion formed by selenium?

Understand the Problem

The question is asking about the ionic charge of selenium when it forms an ion, which is typically obtained by looking at its position in the periodic table and understanding its electron configuration.

More Information

Selenium commonly gains 2 electrons to form an anion with a -2 charge, as it tends to complete its valence shell for stability.

Tips

Ensure clarity between cations and anions, as selenium can technically form both but predominantly forms an anion.
