Yes in the sense that you can have a compound and add a chemical or element to it in order to remove an atom from the compound, thus returning it to its elemental form. For example, KI + Li --> LiI + K. The Potassium (K) was in a compound but is now alone in its elemental form after the reaction. (Lithium can replace Potassium because it is more reactive. See the Activity Series for more info on that).
yes, it is true.
Chemical Bonding
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
Corrosion is not so much a chemical property as it is a chemical process. Since it involves chemical reactions by which chemical compounds become different chemical compounds, that makes it a chemical rather than purely physical process.
Through the magic of chemistry. It's all about the many, many different ways that atoms can be linked up via chemical bonds to make chemical compounds. And because of the "flexibility" of the carbon atom, it can make long chains of complex compounds. These long chains will "up the count" of molecules. As compounds become larger aggregates of atoms, the atoms can arrange themselves in many different ways to become a different compound. Even with the same numbers of the same atoms, different arrangements, and, therefore, distinct compounds with their own unique characteristics, can be formed. The element carbon is almost miraculous in it's ability to form "chains" or other complex structures to give shape to very large, complex molecules. Far and away more compounds are formed from carbon than any other single element.
An chemical element cannot loss a chemical element. Probable you think to the last member of a radioactive decay chain.
Elements become compounds after chemical reactions.
Yes. Compounds can undergo chemical changes to become elements. An example would be the following: Zn(s) + CuCl2(aq) ===> ZnCl2(aq) + Cu(s). THe CuCl2 is a compound and it is changed into the element Cu(s) and also into zinc chloride.
The elements or molecules that participate in a chemical reaction and yield a product.
Chemical Bonding
Because there is no chemical reaction, the properties of the elements and compounds do not change when they form a mixture.
Elements combine to form compounds to become more stable
Any compound can in some way be broken down into its elemental constituents (although they may spontaneously partially or entirely recombine afterwards). One method that will always do this is thermal decomposition, or thermolysis. In this chemical process the compound is simply heated to a high enough temperature that all the chemical bonds between the atom break. Another gentler method uses the techniques of chemical analysis, plus some additional steps to separate the elements of the original compound from the elements of the carrier compounds used to separate them from the original compound.
They become 2 or more elements
No. Only radioactive elements, which undergo radioactive decay can change to different elements.

Yes, curium can form chemical compounds.
Most atoms tend to undergo chemical reactions combining in ways that cause their atoms to become more stable
