I think that the answer is "it just is" ive red a few suggestions about it having a full electron shell but i have never seen an adequite and proven explanation

"Mercury is a liquid at room temperature because the "relativistic contraction" of its atomic orbitals makes it behave chemically almost like a noble gas, not wanting to share electrons with other atoms, even other mercury atoms!"
