Electrons.
Valence shell electrons or valence electrons determine the chemical properties of an atom...
The electron shell is the source of an element's chemical properties and the moderator of chemical reactions; the electron shell depends on the protons that constitute the atom
The chemical properties of an object show what a chemical change did to that substance.
eletrons
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).
yes chemical properties do change a substance physical properties just change the physical shape or look!!!
In the chemical reactivity of atoms electrons are involved.
It is a matter of how they are arranged and electrically charged that changes the properties of them
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.
pure substance,and chemical substance,
The chemical properties of an object show what a chemical change did to that substance.
