Antimony is also what is known as a semimetal, which refers to the way in which it conducts energy â bismuth and arsenic are both semimetals as well. Other metalloids include silicon, germanium, and boron. Ad. Antimony in its stable form is a blue-white metallic element, with an atomic mass of 121.76g/mol. It melts at 1167Â°F (630Â°C) and makes a rather effective semiconductor.
