Oxygen and copper are examples of elements; cooper is a barrel maker.
elements and compounds?
The reaction of oxygen with other elements is oxidation. An example is iron and oxygen reacting to form rust.
no, it is a mixture of several elements. elements are what you can see in the periodic table for example Oxygen and Hydrogen.
No, but some of the gasses which make up air are elements (such as oxygen, nitrogen) are elements.
The number of elements in a compound can be determined by looking at the chemical formula and identifying each element's symbol. For example, the compound CO2 has two elements, carbon and oxygen. Another example, glucose, has the formula C6H12O6, and has three elements, carbon, hydrogen, and oxygen.
Compound elements. For example, calcite has the combination of calcium, oxygen, and carbon.
The metal itself and oxygen. For example, in ferrous oxide or ferric oxide, there is iron and oxygen.
Oxygen, carbon, nitrogen, hydrogen, calcium are all elements.
Water, because it contains 2 elements hydrogen and oxygen.
Oxygen, carbon, nitrogen, hydrogen, calcium are all elements.
Xenon is one of the elements. It is a type of gas (another example of a gas is the oxygen we all breathe). It is inert (whereas, for example, oxygen can combine with hydrogen to form water, xenon does not combine with other elements).
The organic components of elements are those that support life. Elements like hydrogen and oxygen bond to create life-sustaining water for example.
