The element silver has both physical and chemical properties, some of which do not change when the size of the sample changes. Which of these choices is a physical property that does not change when the size of the sample changes? flammability volume density reactivity with oxygen

I believe that the answer is density.

Reason being is because the density of an object does not change when an object changes size.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
