What is oxygens charge?

Oxygen typically has a charge of -2 when it forms chemical compounds. This is because oxygen has six valence electrons and requires two more to achieve a stable, full outer electron shell. Oxygen readily gains two electrons to achieve this configuration, resulting in a net charge of -2. This charge is commonly observed in compounds such as water (H2O), carbon dioxide (CO2), and various oxides.

It's important to note that the charge of an oxygen atom can vary depending on the context and the specific compound it is involved with. For instance, in peroxides like hydrogen peroxide (H2O2) or superoxides like potassium superoxide (KO2), oxygen can have a charge of -1 due to its participation in different types of chemical bonds.

In addition to its role in forming chemical compounds, oxygen also plays a crucial role in many biological processes, including respiration and energy production.
