Oxide ion. because oxsgen has 6 electrons in its orbit or subshell, so it needs only two to achieve the octet rule by gaining 2 electrons. Gaining electrons means that the element become an anion ion

Answer:

The correct option is oxide ion

Step-by-step explanation:

In the periodic table, elements (other than noble gases) tend to achieve there duplet/octet electron configuration (having a completely filled outermost shell) by either donating or accepting electrons. Generally, metals donate electrons to become positively charged cations while non-metals accept electrons to become negatively charged anions.

Oxygen accepts two electrons in order to have a fully filled outermost shell and become O²⁻ or oxide ion. Oxygen itself is an element and it's ion is called oxide ion
