All the properties are different for chemical elements and chemical compounds.

Compounds
The elements that compose it and the arrangement of its atoms
The chemical and physical properties of a compound are different than those of the elements from which it is formed.
those elements are in the same 'family' or 'group'
Yes, the properties of compounds are different from those of their component elements. For example, sodium metal and chlorine gas react to form the solid salt sodium chloride.
Compounds
yes. an example is salt. salt is an edible compound that is made of poisonus elements.
no
Molecules have properties that are different from those of the elements of which the molecules are composed.
No. When elements combine to form compounds the resulting chemical properties may be very different from those of the elements that make it. The components of a mixture are not chemically combined and retain their original properties.
No: The compounds more often have very different properties from those of the elements that form them.
When elements combine, the resulting compound is usually very different to the original elements. Take common salt for example. Sodium and chlorine are very reactive elements that you certainly would not allow anywhere near your food, yet sodium chloride is an essential part of our diets.

Yes, this affirmation is true.
