in chromium,the metal-metal interactions are strong due to the presence of six unpaired electronsin the 3d and 4s subshell.on the otherhand all the electrons in the 5d and 6s subshells are paired in mercury and therefore the metal-metal interactions are weak.hence chromium is a typical hard metal while mercury is a liquid
