* Oxide is a compound, not an element. It's formed when oxygen (O) combines with another element.
* Elements are the fundamental building blocks of matter. They cannot be broken down further into simpler substances.
So, to answer your question:
* No element is "made of oxide".
* Many elements form oxides when they combine with oxygen. Examples include:
* Iron oxide (FeO): Rust
* Aluminum oxide (Al2O3): Found in bauxite ore
* Silicon dioxide (SiO2): Sand and quartz
If you're wondering about a specific element, please let me know and I can tell you what oxide it forms.
