Elements are not mixture of all. An element entirely of atoms of the same type.
Pure elements cannot be mixtures.
Chemical elements are not mixtures (I do not think to the isotopic composition).
Yes, all the mixtures contain compounds or elements.
No, they are mixtures.
No they are not.
No they are not.
No, elements are the most basic form of a substance, thus mixtures might be made up from different elents but elements can never be made from mixtures.
Mixtures. In mixtures, the elements or compounds are physically combined and can be separated through physical means such as filtration or distillation.
they keep their original properties.
Yes. Everything is composed of elements.
they keep their original properties.
A mixture is composed of two or more substances that are not chemically combined. Elements themselves, such as oxygen, gold, or iron, are pure substances and cannot be mixtures. However, mixtures can contain various elements, such as air (a mixture of gases like nitrogen and oxygen) or alloys (like bronze, which is a mixture of copper and tin). Thus, while elements themselves are not mixtures, they can be components of various types of mixtures.
