An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
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.
Pure elements are found least in nature compared to compounds and mixtures. Most elements exist bonded to other elements to form compounds or mixed with other substances to form mixtures in nature. Pure elements are less common due to their tendency to react and combine with other elements.
false all solutions are mixtures but not all mixtures are solutions
Yes, all the mixtures contain compounds or elements.
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).
All minerals, except the elements and a few exceptions like graphite, are mixtures, or compounds, of elements.
No, they are mixtures.
