The valency of the electron shells
All atoms want to have a full outside shell and do so by either removing, gaining or sharing electrons. If they only have to remove or gain one electron, they will do so quite easily and are reactive.
Chemical properties can only be determined by changing a substance.
physical properties
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
is seen when one substance reacts with another substance
The properties exhibited during a substance's transformation to another substance are known as chemical properties. These characteristics relate to the ability of a substance to undergo chemical changes, such as reactivity with other substances or the formation of new compounds.
The chemical properties of an object show what a chemical change did to that substance.
A substance's characteristic properties are the most recognizable properties of that substance. Chemical properties are exhibited as one substance is chemically transformed into another (e.g., iron rusting).
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
A chemical property is the properties exhibited by a material in a chemical reaction. This gives a substance the ability to have a chemical identity and is also used in building chemical classifications. The properties can be used in identifying a substance that is unknown or to separate substances. The property also helps in providing information on the application of a substance.

Chemical properties
A chemical reaction (change) results in a change in chemical properties.
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
Physical properties are it's rest quantitative properties, while the chemical properties are its reactions to things like temperature and other substances. I hope somebody gives you a more comprehensive answer. :)
