When elements form compounds by combining with other element(s) then they
form positive or negative ions(i.e gains a positive or a negative charge) to bring about combination.As the positive and negative ions attract each other with a strong chemical bond (electrovalent or covalent) they combine with each other to form compound. Thus the reactant elements are actually present in the produced compound as metal or non-metals ions.
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.
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.
No they are not.
Mixtures. In mixtures, the elements or compounds are physically combined and can be separated through physical means such as filtration or distillation.
to get the original elements of it
they keep their original properties.

i think it is a earth have spoilt.

When elements form mixtures, they will never gain or lose electrical charge and stay exactly the same as they were before, as no chemical reaction has occured (i.e. no change in amount of neutrons)
Elements, mixtures, etc
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
Pure elements cannot be mixtures.
Yes, besides elements and compounds, matter can exist in form of mixtures.
It is a physical process, not a chemical reaction.
Chemical elements are not mixtures (I do not think to the isotopic composition).
