gold can be flattened into an extremely thin sheet. the malleability of gold is due to the
(1) radioactive decay mode of the isotope au-198
(2) proton-to-neutron ratio in an atom of gold
(3) nature of the bonds between gold atoms
(4) reactivity of gold atoms

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
