<DIV><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Why is mercury a liquid under Earth surface conditions? The elements around it on the periodic table have much higher melting points. I have been hunting for an answer, but have not found substantial. Obviously, it involves the forces holding the mercury atoms together. However, I cannot think why mercury would be so different from other metals. One source mentioned its atomic radius, but other metals have similar sizes and still have high melting points.</SPAN></DIV>
