Yes, mercury is indeed a heavier element than tin. To understand this, we can look at their respective densities and atomic weights. Mercury has an atomic weight of approximately 200.59 g/mol, while tin has an atomic weight of about 118.71 g/mol. This means that, on average, mercury is significantly heavier than tin at the atomic level.
Furthermore, when we consider their densities, mercury has a density of about 13.6 g/cm³, whereas tin’s density is around 7.31 g/cm³. This further emphasizes the fact that mercury is not only heavier in terms of atomic weight but also much denser than tin. So, if you were to compare equal volumes of both elements, mercury would weigh much more than tin.
