Oxygen is located in Group 16 of the periodic table. This means it has 6 electrons in its outermost shell.

In order to achieve a stable electron configuration, oxygen needs to have a full outer shell of 8 electrons. This is known as the "octet rule".

To achieve this, oxygen can gain two electrons from another atom. When it does this, it becomes negatively charged because it now has more electrons (which are negatively charged) than protons (which are positively charged).

This negatively charged oxygen atom is known as an oxide ion. It is represented as O^2- , indicating that it has gained two electrons.
