Which term describes a metal that has a higher concentration of oxygen and is considered more resistant to corrosion?

The term that describes a metal with a higher concentration of oxygen, which is considered more resistant to corrosion, is noble. Noble metals, such as gold, platinum, and sometimes silver, have a strong affinity for stability and do not easily react with oxygen or other substances in their environment. This inherent stability leads to their resistance to corrosion, making them less likely to form oxides or other corrosion products when exposed to various environments.

In contrast, basic metals may have different properties related to pH levels rather than corrosion resistance. Active and reactive metals tend to corrode more readily as they often more willingly engage in chemical reactions, including oxidation processes. Therefore, the term 'noble' accurately encompasses the idea of corrosion resistance due to the metal's chemical stability and tendency to avoid oxidation, aligning perfectly with the question's context.
